-4%28u-5%29=7u-13 Start with the given equation.


-4u%2B20=7u-13 Distribute.


-4u=7u-13-20 Subtract 20 from both sides.


-4u-7u=-13-20 Subtract 7u from both sides.


-11u=-13-20 Combine like terms on the left side.


-11u=-33 Combine like terms on the right side.


u=%28-33%29%2F%28-11%29 Divide both sides by -11 to isolate u.


u=3 Reduce.
