Question

mel is 5 years older than Rafie and anna is twice as old as rafie. the sum of their age is 57. how old is mel?

Answer 1

Answer:

Mel is 18.

Step-by-step explanation:

57 = x + (5 + x) + (2x)

57 = x + 5 + x + 2x

57 = (x + x + 2x) + (5)

57 = 4x + 5

57 - 5 = 4x + 5 - 5

52 / 4 = 4x / 4

13 = x
