6y – 20 = 2y – 4. A. y = 2 B. y = 4 C. y = 3 D. y = 16

"Given:

Solution:

Apply additive inverse of 2y and -20 to both sides.

Evaluate: 6y - 2y = 4y, -20 + 20 = 0, 2y - 2y = 0 and -4 + 20 = 16.

Divide both sides by 4 so that the y will have a coefficient of 1.

Evaluate: 4y ÷ 4 = 1y or y and 16 ÷ 4 = 4.

Answer:

B. y = 4"
