#

blissful vapor Yo

with what ?

blissful vapor Jun 20, 2023, 10:25 AM

#

D

#

d

#

I I've watched videos but there's none that complex

#

And idk how to do it

#

@serene python

verbal agate Jun 20, 2023, 10:26 AM

#

well for the 2x+4/2

#

you can simplify that

#

its just x+2

blissful vapor Jun 20, 2023, 10:27 AM

#

ok

#

nice i understand better know gimme a sec

verbal agate Jun 20, 2023, 10:27 AM

#

it just makes it a lot simpler and easier to solve

blissful vapor Jun 20, 2023, 10:27 AM

#

so i have the exam in 10 mins

#

should i just simply those questions as much as i can

#

what about the bottom one what should i do there

verbal agate Jun 20, 2023, 10:28 AM

#

at that point just distribute the 5 with the rest of the terms in the parantheses

#

oh btw for the top one you can also multiply both sides by 2 to get rid of the fraction

blissful vapor Jun 20, 2023, 10:29 AM

#

fuck me im gonna fail

verbal agate Jun 20, 2023, 10:29 AM

#

so if u multiply both sides by 2, you would get 14x-18y-(2x+4)=-30

verbal agate Jun 20, 2023, 10:29 AM

#

blissful vapor fuck me im gonna fail

no u wont

blissful vapor Jun 20, 2023, 10:30 AM

#

Yh I understand better know that the fractions gone

verbal agate Jun 20, 2023, 10:30 AM

#

alr

#

thats good

#

Don't mind the top one does this look good

#

@verbal agate

verbal agate Jun 20, 2023, 10:31 AM

#

hm

blissful vapor Jun 20, 2023, 10:31 AM

#

then i do the same thing to the bottome one

verbal agate Jun 20, 2023, 10:31 AM

#

i got x=3y/2-13/6

blissful vapor Jun 20, 2023, 10:32 AM

#

alr wish me luck

#

my year depends on this

verbal agate Jun 20, 2023, 10:32 AM

#

oh rlly

#

well good luck on it

blissful vapor Jun 20, 2023, 10:32 AM

#

Yh

#

Have 3 exams today

#

Dumb schedule

verbal agate Jun 20, 2023, 10:34 AM

#

blissful vapor

oh i see what u did for this one

#

when you got rid of the fraction the expression should be 7x-9y-(x+2)

#

not 7x-9y-x+2

#

and so for this one you would simplify that to be 7x-9y-x-2

#

@blissful vaporis ur exam starting now?

blissful vapor Jun 20, 2023, 10:35 AM

#

@verbal agate

verbal agate Jun 20, 2023, 10:35 AM

#

yes?

blissful vapor Jun 20, 2023, 10:36 AM

#

I'm using a method called igualation or sonething

verbal agate Jun 20, 2023, 10:36 AM

#

whats that?

blissful vapor Jun 20, 2023, 10:36 AM

#

Idk how to explain but there's 3 methods

verbal agate Jun 20, 2023, 10:36 AM

#

oh

#

well you can use whatever method you feel comfortable with

This but obv that's more complicstef

#

Complicated

verbal agate Jun 20, 2023, 10:37 AM

#

i see

blissful vapor Jun 20, 2023, 10:37 AM

#

In the question I showed you

verbal agate Jun 20, 2023, 10:37 AM

#

ye

blissful vapor Jun 20, 2023, 10:37 AM

#

So would that work

verbal agate Jun 20, 2023, 10:38 AM

#

i have never heard of igualation method

blissful vapor Jun 20, 2023, 10:38 AM

#

Idk it's taught in Spanish dchools

#

Schools

#

Do you get it tjo

#

Tho

verbal agate Jun 20, 2023, 10:38 AM

#

oh

#

yeah

blissful vapor Jun 20, 2023, 10:39 AM

#

Would that work

#

In my exam

verbal agate Jun 20, 2023, 10:39 AM

#

im pretty sure it would

#

for the second equation if you use igualation method, you need to solve for x since you solved for x for the top one

#

and then substitute both of the equations and solve for y

blissful vapor Jun 20, 2023, 10:40 AM

#

Is x the same in both yh

verbal agate Jun 20, 2023, 10:41 AM

#

what do you mean

blissful vapor Jun 20, 2023, 10:41 AM

#

In the top and bottom one

verbal agate Jun 20, 2023, 10:41 AM

#

2x+5(x-1+y)-5=20+2x

#

2x+5x-5+5y-5=20+2x

#

5x+5y=25

blissful vapor Jun 20, 2023, 10:42 AM

#

Yh

verbal agate Jun 20, 2023, 10:42 AM

#

5x=25-5y

blissful vapor Jun 20, 2023, 10:42 AM

#

Yj

verbal agate Jun 20, 2023, 10:42 AM

#

x=5-y

blissful vapor Jun 20, 2023, 10:42 AM

#

Yh

#

Or x=25 divided by 5y

#

Yh

verbal agate Jun 20, 2023, 10:43 AM

#

so then by igualation method, 5-y=3y/2-13/6

blissful vapor Jun 20, 2023, 10:43 AM

#

I gtg

verbal agate Jun 20, 2023, 10:43 AM

#

and then solve for y

blissful vapor Jun 20, 2023, 10:43 AM

#

Exam starting

verbal agate Jun 20, 2023, 10:43 AM

#

oh

#
