Question

4x - 2y = 8 8y = -16x - 32

Answer 1

4x - 2y = 8 ------equation 1
8y = -16x - 32 ------equation 2

you can do either elimination and substitution method.
Let's do substitution.
Divide the whole equation 2 by 8

Answer 2

what did you get?

Answer 3

multiply equation with 4 and then add it with equation 2
you will get the value of x

Answer 4

4x-2y=8

8y=-16x -32 this is the equal 16x +8y =-32 divide both sides by 4
and will get 4x +2y = -8 so your exercise wil be in this case

4x -2y = 8
4x +2y = -8
------------ add them and will get
8x 0 = 0

8x=0
x=0

4*0 -2y = 8
0 -2y = 8
2y= -8
y = -4

x=0
y=-4

hope this is understandably
