1x+15-13x\geq 51
Subtract 13x from both sides.
-12x+15\geq 51
Combine 1x and -13x to get -12x.
-12x\geq 51-15
Subtract 15 from both sides.
-12x\geq 36
Subtract 15 from 51 to get 36.
x\leq \frac{36}{-12}
Divide both sides by -12. Since -12 is negative, the inequality direction is changed.
x\leq -3
Divide 36 by -12 to get -3.
