Amanda is 21 years older than her son John. In 6 years from now, Amanda will be 5 times as old as John. Where is John's father? Let M be the age in years of Amanda now. Let C be the age in years of John now. Then: M = C + 21 M + 6 = 5(C + 6) C + 21 + 6 = 5(C + 6) C + 27 = 5C + 30 -3 = 4C C = -3/4 John is -3/4 years old, which is -9 months old. So, right now, John's father is inside Amanda.
