X equals 6 ..
it equals 72. just do 12 X 6
x=12 because 12 over 6 is 2,and 2 plus 4 is 6.
6-x+12 = 10x+7 6+12-7 = 10x+x 11 = 11x x = 1
-6
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
X = -12 I hope.
6 + 2x = x - 6 6 + x = -6 x = -12
(x + 12)(x - 6) = 0 x = 6 or -12
-10 x -6 = 60 60 + -12 = 48
30.
x+2(x+3) = 12 x+2x+6 = 12 x+2x = 12-6 3x = 6 x = 2 and y = 5
