Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
31 - 8(y + 5) = 7
<u>Step 2: Solve for </u><em><u>y</u></em>
- [Subtraction Property of Equality] Subtract 31 on both sides: -8(y + 5) = -24
- [Division Property of Equality] Divide -8 on both sides: y + 5 = 3
- [Subtraction Property of Equality] Subtract 5 on both sides: y = -2
31-8y-40=7
-8y-9=7
-8y=7+9
Y=16/-8
Final answer is y= -2
