7-2x+6\geq 25
Use the distributive property to multiply -2 by x-3.
13-2x\geq 25
Add 7 and 6 to get 13.
-2x\geq 25-13
Subtract 13 from both sides.
-2x\geq 12
Subtract 13 from 25 to get 12.
x\leq \frac{12}{-2}
Divide both sides by -2. Since -2 is negative, the inequality direction is changed.
x\leq -6
Divide 12 by -2 to get -6.
