There are two ways to do this:

Method # 1


5%28x-1%29=50 Start with the given equation.


5%2811-1%29=50 Plug in x=11


5%2810%29=50 Subtract


50=50 Multiply


Since the equation is true, this means that x=11 is a solution.




Method # 2

5%28x-1%29=50 Start with the given equation.


5x-5=50 Distribute.


5x=50%2B5 Add 5 to both sides.


5x=55 Combine like terms on the right side.


x=%2855%29%2F%285%29 Divide both sides by 5 to isolate x.


x=11 Reduce.

Answer:

So the solution is x=11
