-3x-42\geq 4x-7
Multiply both sides of the equation by -3. Since -3 is negative, the inequality direction is changed.
-3x-42-4x\geq -7
Subtract 4x from both sides.
-7x-42\geq -7
Combine -3x and -4x to get -7x.
-7x\geq -7+42
Add 42 to both sides.
-7x\geq 35
Add -7 and 42 to get 35.
x\leq \frac{35}{-7}
Divide both sides by -7. Since -7 is negative, the inequality direction is changed.
x\leq -5
Divide 35 by -7 to get -5.
