11x = 8x-6.............. 11x-8x = -6................... 3x= -6 x = -2
11x(2x - 1) = 0 so either 11x = 0 or x = ½
-7+11x = 9-5x 11x+5x = 9+7 16x = 16 x = 1
11x - 21 = 7x + 3 4x = 24x = 6
180=11x+9x. 180 = 20x. 18=2x. 9=x.
-11x-27=-49 11x+27=49 11x=22 x=2
To solve for x: x2 = 11x - 10 x2 - 11x = -10 x2 - 11x + 10 =0 (x - 1)(x - 10) = 0 x = {1, 10)
x = -1.7
x2 = 11x - 10 ∴ x2 - 11x + 10 = 0 ∴ (x - 10)(x - 1) = 0 ∴ x ∈ {1, 10}

Solving 11x-28=82x for x involves the following: -28=82x-11x -28=71x -28/71=x x=.3943 (truncated to 4 decimal places)
x2 = -11x - 10 x2 + 11x + 10 = 0 (x + 1)(x + 10) = 0
12x = 11x - 5, subtract both sides by 11x x = -5
x=3
11x = 8x-6.............. 11x-8x = -6................... 3x= -6 x = -2
11x(2x - 1) = 0 so either 11x = 0 or x = ½
