Answer:

x=2

y=5

Step-by-step explanation:

Lets start by solving for y. Multiply the bottom equation by -2. This gives you:

3x+2y=16

-14x-2y = -38

Your x's cancel out in this situation, giving you:

-11x=-22

Solving this gives you x=2.

After this, plug-in 2 for your x's.

3(2) + 2y = 16

6 + 2y = 16

2y = 10

y = 5
