If 5x plus 2x plus 3x plus 10x equals 140 What is x?
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
