16x%2B21=30%2B13x Start with the given equation.


16x=30%2B13x-21 Subtract 21 from both sides.


16x-13x=30-21 Subtract 13x from both sides.


3x=30-21 Combine like terms on the left side.


3x=9 Combine like terms on the right side.


x=%289%29%2F%283%29 Divide both sides by 3 to isolate x.


x=3 Reduce.
