Question

Solve the system by substitution:
-4.5x-2y=-12.5
3.25x-y=-0.75

Answer 1

solve 3.25x-y=-0.75
for y

Answer 2

okay would that be?... @♂
3.25x-y=-0.75
-3.25x -3.25x
-y=-0.75-3.25x

Answer 3

\(-4.5x-2y=-12.5
\\3.25x-y=-0.75\)

\(3.25x+0.75=y\) now you can plug that into the first equation

Answer 4

Like this? @♂
-4.5x-2(3.25x+0.75)=12.5

Answer 5

exactly except the 12.5 is negative

Answer 6

Okay cool thank you! Is that all that I have to do for the answer? Or is there more steps? @♂

Answer 7

well you have to solve for y and x

Answer 8

How exactly would I do that? I'm sorry I am not the best at this... @♂

Answer 9

I messed up my math, I'ms upposed to have x=1
