4%2F%28x%2B1%29=2%2F5 Start with the given equation.


4%2A5=2%28x%2B1%29 Cross multiply


20=2%28x%2B1%29 Multiply


20=2x%2B2 Distribute.


0=2x%2B2-20 Subtract 20 from both sides.


-2x=2-20 Subtract 2x from both sides.


-2x=-18 Combine like terms on the right side.


x=%28-18%29%2F%28-2%29 Divide both sides by -2 to isolate x.


x=9 Reduce.
