x=7 look at the bottom for the reason:
First, when a number and a variable are placed next to each other it means to multiply the 2. (example- what is 3x if x=7 ? Well, 3x7=21 so, 3x=21)
so, 5x + 2x + 3x + 10x = 140
20x = 140
40/20 = 7 so,
(5x7) + (2x7) + (3x7) + (10x7) = 140 so,
35 + 14 + 21 + 70 = 140
