c = 3

5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.

If: x/3 + 10 = 15 Then: x = 15

3n + 15 equals 3 times the number n, the answer to which is increased by 15. It can only be evaluated if the value of n is known. The expression can be factorised but that is of marginal help in evaluating it.
