Answer: x=5

Step-by-step explanation:

5 x 5 = 25 - 7 = 18

        so x=5

Answer: x = 125

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x/5 - 7 = 18

1/5x + -7 = 18

1/5x + -7 = 18

Step 2: Add 7 to both sides.

1/5x - 7 + 7 = 18 + 7

1/5x = 25

Step 3: Multiply both sides by 5.

5 * (1/5x) =  (5) * (25)

x = 125
