x=18
x=18
x - 13 = 5 x = 18
x-18=34 solve for x add 18 both sides x-18+18=34+18 x=52
1/9=x/18 18=9x 2=x
2x^3(x - 3)(x + 3)
0.5x=18 x=36
2x2 - 9x = 18 2x2 - 9x -18 = 0 (2x - 18)(x + 9) x= -9 and 9
x = -1 Since -3(-1) + 15 = 18
use algebra and then factor... x= -9 and 9
3(x+2) = x -18 3x+6 = x -18 3x -x = -18 -6 2x = -24 x = -12
2x - 8 = 10 2x = 10 + 8 2x = 18 x = 18 / 2 x = 9
