Solve for the unknown in the equation.

5(x-4) = 25

**Solution:-**

Eliminate the parentheses.

5x – 20 = 25

Add the known value to both sides of the equation.

5x – 20 + (20) = 25 + (20)

Now simplify.

5x = 45

Divide both sides of the equation by the known factor to isolate the unknown value.

Now simplify.

x = 9

Check the solution by substituting the answer in the original equation and verifying that a true statement results.

The answer checks, so the solution of the equation is 9.
