3x+10>5x-10+2x
Add -3 and 13 to get 10.
3x+10>7x-10
Combine 5x and 2x to get 7x.
3x+10-7x>-10
Subtract 7x from both sides.
-4x+10>-10
Combine 3x and -7x to get -4x.
-4x>-10-10
Subtract 10 from both sides.
-4x>-20
Subtract 10 from -10 to get -20.
x<\frac{-20}{-4}
Divide both sides by -4. Since -4 is negative, the inequality direction is changed.
x<5
Divide -20 by -4 to get 5.
