5y + (86 - y) = 86 + 4y

0

Step-by-step explanation:

Given

5y + (86 - y) = 86 + 4y

Open parenthesis

5y + 86 - y = 86 + 4y

Rearrange the expression

5y - y + 86 = 86 + 4y

4y + 86 = 86 + 4y

Combine like terms

4y - 4y = 86 - 86

0 = 0

0

All real values, (-∞, ∞)

Step-by-step explanation:

Step 1: Distribute

5y + (86 - y) = 86 + 4y

5y + 86 - y = 86 + 4y

Step 2: Combine like terms

5y + 86 - y = 86 + 4y

4y + 86 = 86 + 4y

Step 3: Subtract 4y from both sides

4y + 86 - 4y = 86 + 4y - 4y

86 = 86

Step 4: Subtract 86 from both sides

0 = 0

Answer: All real values, (-∞, ∞)
