3x-21\leq 35+7x
Multiply both sides of the equation by 7. Since 7 is positive, the inequality direction remains the same.
3x-21-7x\leq 35
Subtract 7x from both sides.
-4x-21\leq 35
Combine 3x and -7x to get -4x.
-4x\leq 35+21
Add 21 to both sides.
-4x\leq 56
Add 35 and 21 to get 56.
x\geq \frac{56}{-4}
Divide both sides by -4. Since -4 is negative, the inequality direction is changed.
x\geq -14
Divide 56 by -4 to get -14.
