Answer: d = 4
Step-by-step 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
