Which expression is an equivalent expression for 2(6y - 4)?

• 8y - 2

• 4(3y - 2)

• 12(y - 1)

• 12y - 4

Answer explanation

To simplify 2(6y - 4), distribute the 2: 2 * 6y - 2 * 4 = 12y - 8. The expression 4(3y - 2) also simplifies to 12y - 8, making it equivalent. Thus, 4(3y - 2) is the correct choice.
