Let x represent the unknown nimber. Set up the equation and solve (15% is the same as .15) .15 * x = 18 (next divide both sides by .15 to solve for x) x = 120 15% of 120 = 18

x-18=34 solve for x add 18 both sides x-18+18=34+18 x=52
458 x 2 = 916
x=18
2x + 3(x -4) = 18
x=18
x - 13 = 5 x = 18
1/9=x/18 18=9x 2=x

3(x + 2) = x - 18 3x + 6 = x - 18 3x - x = -18 - 6 2x = -24 x = -12
