5x+35\leq 3x-7
Use the distributive property to multiply 5 by x+7.
5x+35-3x\leq -7
Subtract 3x from both sides.
2x+35\leq -7
Combine 5x and -3x to get 2x.
2x\leq -7-35
Subtract 35 from both sides.
2x\leq -42
Subtract 35 from -7 to get -42.
x\leq \frac{-42}{2}
Divide both sides by 2. Since 2 is positive, the inequality direction remains the same.
x\leq -21
Divide -42 by 2 to get -21.
