Can yall tell me whats wrong here

[sonic barn]

I don't see whats wrong or right about it

[visual yarrow]

I think the mistake is here, you had 5x + 2 = 4
And then it became 5x = 4 + 2 instead of 5x = 4 - 2

[sonic barn]

Oh thx

Hum its still not adding up

[visual yarrow]

What do you mean

[sonic barn]

Wait lemme re check it

[visual yarrow]

Also here, take it step-by-step
x + y = 1
y = 1 - x

[sonic barn]

5x=4-2
5x=2
You divide 5 and 2 to 5 so it cancels 5 and 2 becomes 2/5

X=2/5

If
X=2/5
And
Y=-0.2

If you substitute that to 3x+2y=4

The answer isnt 4=4

[sonic barn]

Isnt that what i did but shorter?

[visual yarrow]

x + 1 ≠ 1 - x

[lucid quiver]

easy ass algebra

[visual yarrow]

x = 2/5
y = 1 - 2/5
5/5 - 2/5 = 3/5 => 0.6

[lucid quiver]

u can't do that on ur own gang

[sonic barn]

Im new to this

[lucid quiver]

im playin

u good bro

[visual yarrow]

are you good at linear algebra?

[lucid quiver]

im good at everything

are u?

nah ima chill

that's easy though

[visual yarrow]

Then explain to me how I find the dim of im(T) and what the im(T) is

[lucid quiver]

bro that's ur homework

stop cheating

[visual yarrow]

ok brochacho

[visual yarrow]

Look, the mistake is here as well

You replaced y incorrectly

It supposed to be 3x + 2(1 - x) = 4

[sonic barn]

Yo thx ive solved it

[crimson creek]

,,x+y=1 \implies x-1=-y \text{ or } 1-x=y
