Question

Enrique is 7 years older than Erin. In 3 years the sum of their ages will be 57. How old is Enrique now?

Answer 1

ok

Enrique = e

Erin = n

e = n + 7

e + n = 57 - 6

e + n = 51

Solve by substitution

n + 7 + n = 51

2n = 51 - 7

2n = 22

n = 22/2

n = 11

e = n + 7

e = 11 + 7

e = 18

Right now Enrique is 18 years old
