2x+7-4x\geq -5
Subtract 4x from both sides.
-2x+7\geq -5
Combine 2x and -4x to get -2x.
-2x\geq -5-7
Subtract 7 from both sides.
-2x\geq -12
Subtract 7 from -5 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.
