Question

Solve the system by substitution......

Answer 1

(4,8) is the answer.

Explanation:

To solve by substitution, you need to isolate a variable. The bottom equation already has y isolated, so we can just plug that into the other equation:

`2x=-2x+16`

Add
`2x` to both sides in order to get rid of the
`-2x` on the right side:

`4x=16`

Now divide by 4 on both sides to get:

`x=4`

That gives us our x. Now plug in that x into either equation. I will just choose the bottom equation:

`y=2(4)\\y=8`

Therefore the solution to this problem is (4,8).
