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
