Answer:
y = 31x +2z -16
Explanation:
You solve this the same way you solve any 2-step linear equation.
Step 1: Subtract the terms that don't include y.
31x +2z -y -(31x +2z) = 16 -(31x +2z)
-y = 16 -31x -2z . . . . . . . . . simplify
Step 2: Divide by the coefficient of y. (Equivalently, multiply by -1.)
y = -16 +31x +2z

I don't like leading minus signs, so I would rearrange the terms:
y = 31x +2z -16
