Question

Solve the system by substitution......

Answer 1

Answer:

(4,8) is the answer.

Step-by-step 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).
