1) 18h = 252 You divide each side by 18, so you can get "h" alone on a side, and its value on the other side of the equation. (18h)/18 = 252/18 h = 14 (Answer C)
2) 31d = 186. Same Thing, you divide each side by 31, so you can get "d" alone on a side, and its value on the other side of the equation. (31d)/31 = 186/31 d= 6 (Answer B)
3) 55c = 385 Again, same thing, You divide each side by 55, so you can get "c" alone on a side, and its value on the other side of the equation. (55c)/55 = 385/55 c = 7 (Answer B)
4) 50w = 1050 You divide each side by 50, so you can get "w" alone on a side, and its value on the other side of the equation. (50w)/50 = 1050/50 w=21 (Answer A)
As you can notice, they all follow the same steps: dividing by the coefficient of the variable both sides, so you can the variable alone on the first side of the equation, and its value on the second side.
