Question

Jacky and Rudy had the same number of stickers. After receiving 72 stickers from Rudy, Jacky had 3x as many stickers as her. How many stickers did they have altogether?
Steve
They each started out with x. So, together they had 2x stickers.

x+72 = 3(x-72)
x+72 = 3x-216
2x = 288

2X/2=288/21
X=44 ,Linear equation. :)
