-12x+18\leq -3\left(2-x\right)
Use the distributive property to multiply -6 by 2x-3.
-12x+18\leq -6+3x
Use the distributive property to multiply -3 by 2-x.
-12x+18-3x\leq -6
Subtract 3x from both sides.
-15x+18\leq -6
Combine -12x and -3x to get -15x.
-15x\leq -6-18
Subtract 18 from both sides.
-15x\leq -24
Subtract 18 from -6 to get -24.
x\geq \frac{-24}{-15}
Divide both sides by -15. Since -15 is negative, the inequality direction is changed.
x\geq \frac{8}{5}
Reduce the fraction \frac{-24}{-15} to lowest terms by extracting and canceling out -3.
