Question

PLZ HELP ASAP!!!
I need help with part a and b

Answer 1

We need to keep y on the left side only.

so we distribute the 4x to the right side.

that means:

4x - 4y = 8

-4x -4x

-4y = 8 - 4x

Now we divide by -4 on both sides

y = 8 - 4x/-4

-2 + x is y

Now for number 2:

Let's use -10 for x.

-2 -10 = -12

Answer 2

ok so 4x-4y=8

4x-4×8=

4x-32

4x-10-32=

-40 -32= -72

I think this is right sorry if I'm wrong
