-18x - 36 + 36 - 12X = -14 (Distribute the 18 and multiply 18(-x), which is -18x as well as 18(-2), which is -36. Also distribute the -4 and multiply -4(-9) which is 36 as well as -4(3x) which is -12x).
-30X = -14 (Combine like terms and add -36 + 36, which is 0. Then add -18x - 12X, which is -30 X)
= (divide both sides by -30 to isolate the "X")
(a negative divided by a negative is a positive)
(reduce the fraction of by dividing the numerator and denominator by 2)
