Question

Solve this equation. Enter your answer in the box.

–24 + 12d = 2(d – 3) + 22
d = ————

Answer 1

Answer: d = 4

Explanation:

-24 + 12d = 2(d - 3) + 22

Multiple the 2 with whats in the parentheses

-24 + 12d = 2d - 6 + 22

Subtract both sides by 2d ( 12d - 2d )(2d - 2d is cancelled out)

-24 + 10d = -6 + 46

Add 24 to both side ( 22 + 24 )( -24 + 24 is cancelled out)

10d = -6 + 46

10d = 40 (Add -6 + 46 to get 40)

Divide both sides by 10

b = 4
