14x - 14 = 2x + 46 14x - 2x = 46 + 14 12x = 60 x = 5
-14x
x2 - 14x = -49 ∴ x2 - 14x + 49 = 0 ∴ (x - 7)2 = 0 ∴ x = 7

-14x-7 = 35 -14x = 35+7 -14x = 42 x = -3

As written, that equals 325 - 14x which is in its simplest form.
14x - 14 = 2x + 46 14x - 2x = 46 + 14 12x = 60 x = 5
-14x
x2 - 14x = -49 ∴ x2 - 14x + 49 = 0 ∴ (x - 7)2 = 0 ∴ x = 7
(14x)(x)+1 14x^2 + 1
3x-7 = 14x-29 29-7 = 14x-3x 22 = 11x x = 2 Hope that helps!!;)
