Please look in your text book for this problem Statement

The equation is x 5 = 22.

Apply addition property of equality: Add 5 to each side.

x 5 + 5 = 22 + 5

x + 0 = 22 + 5             (Apply additive inverse property: 5 + 5 = 0)

x = 22 + 5                   (Apply additive identity property: x + 0 = x)

x = 17                         (Add: 22 + 5 = 17)

Check:

To check the solution, substitute x = 17 in original equation.

x 5= 22 17 5 = 22

22 = 22                   (Subtract: 175= 22)

The statement is true.

The value of x = 17.
