2+x-4 = 12 x = 12+4-2 x = 14
9x + 2 = 12x + 14 -3x = 12 x = -4
-14 = 3x + (x-2)-14 = 3x + x -2-14 = 4x -2-12 = 4x-3 = x
x = 0
(12x6)+(14/7)72+274
3x+50=6x+14 50-14=6x-3x 36=3x x=36 / 3 therefore x=12
it equals 72. just do 12 X 6
x=6Solution:x + 2x + 14 = 5x + 214 - 2 = 5x - 3x12 = 2xx = 12/2 = 6
12 x 12 + 14 = 158
simplify it, 7x-12=x+2+2x-3x 7x=2+12+3x-3x 7x=14 x=2
