Step-by-step explanation:

Step 1: Define

Identify

31 - 8(y + 5) = 7

Step 2: Solve for y

1. [Subtraction Property of Equality] Subtract 31 on both sides:                       -8(y + 5) = -24
2. [Division Property of Equality] Divide -8 on both sides:                                y + 5 = 3
3. [Subtraction Property of Equality] Subtract 5 on both sides:                        y = -2

Answer 2

31-8y-40=7
-8y-9=7
-8y=7+9
Y=16/-8

Final answer is y= -2
