@sharp pebble what grade / level of education are you at?

#

just as a general thing

#

ok alright

#

so let's see. are you familiar with such operations as "add ___ to both sides" or "multiply by ___ on both sides"?

#

don't really know what "it adds together" would mean

#

i'll be right back

#

well the equation says -5 - x

#

so it is -5 - x

#

for a first step, i'd recommend multiplying both sides by -1. that way you will get rid of all the minus signs, and have less room for error

#

do you understand what to do?

#

yes i know

#

the solution of 6x+11=0 is not x = 1.83330

#

anyway i am guiding you towards the solution

#

it will not be one step

#

in order for me to help you, you'll need to follow instructions

empty stone
#

bring x terms to one side

#

and the number to other

#

?????

As a helper, please do not give out answers that could be copied as a homework solution. Have the student work through the problem themselves and guide them along the way.

@sharp pebble are you willing to follow instructions? yes or no

empty stone
#

spooky

open geyser
#

ok, yes, that is correct so far.

#

the original equation is -5-x = -4x-13

op added x, and then 13, to both sides

#

and then collected like terms

empty stone
#

yes

#

but

#

-5+13

open geyser
#

oh, yes, there's a sign error.

empty stone
#

...

#

yeah

open geyser
#

only spotted it now, my bad.

empty stone
#

np

#

ye

open geyser
#

from -3x = 8, you divide both sides by -3

#

and get x = -8/3

#

unless the problem instructed you to answer as a decimal, i would leave -8/3 as is.

#

??

empty stone
#

?

open geyser
#

do you want "simplest form" or do you want "decimals"?

empty stone
#

what does simples form in decimals mean

#

ddoesn't make sense

#

ssurely its one or the other

#

simple form is fraction

open geyser
#

missing minus sign, also doesn't answer my question.

#

ok, so the problem said explicitly "Write your answer as a decimal". yes?

#

mb then

#

peace

open geyser
#

yes, in that case x = -2.(6) is correct.

#

(for the first problem)

#

so far so good

#

for future reference, standard policy on this server for problems written in non-English languages is to send a picture in the original language and then supply a translation

#

no

#

careful on the right

#

what does x - x simplify into?

#

yes

#

so you are left with the equation -1 = 0

#

yw

#

do you have anything else to ask?

#

ok
