Answer:
y = -2
Step-by-step explanation:
Plug in 3 for x and you get:
15 + 3y = 9
Solve for, Subtract 15 oon both sides:
3y = -6
Divide by 3 on both sides:
y = -2
Answer:
y = -2
Step-by-step explanation:
Substituting x for 3 we get
5(3) + 3y = 9
Since both sides are divisible by three, we do that
5 + y + 3
Isolate y
y = -2
