The equation is 27 + n = 46.

(Apply subtraction property of equality: If a = b, then )

27 + n – 27 = 46 – 27     (Subtract 27 from each side)

n = 46 – 27                      (Apply additive inverse property: 27 – 27 = 0)

n = 19                               (Subtract: 46 – 27 = 19)

Check:

To check the solution substitute n = 19 in original equation.

27 + 19 = 46

46 = 46                            (Add: 27 + 19 = 46)

The equality is true.

The value of n = 19.
