2x-3x+21\leq 3
Use the distributive property to multiply -3 by x-7.
-x+21\leq 3
Combine 2x and -3x to get -x.
-x\leq 3-21
Subtract 21 from both sides.
-x\leq -18
Subtract 21 from 3 to get -18.
x\geq \frac{-18}{-1}
Divide both sides by -1. Since -1 is negative, the inequality direction is changed.
x\geq 18
Fraction \frac{-18}{-1} can be simplified to 18 by removing the negative sign from both the numerator and the denominator.
