Question 457222
x = son's age now
6x = father's age now {father is six times as old as his son}


x - 2 = son two years ago
6x - 2 = father two years ago


6x - 2 = 8(x - 2) {two years ago the father was eight times as old as his son}
6x - 2 = 8x - 16 {used distributive property}
-2 = 2x - 16 {subtracted 6x from both sides}
14 = 2x {added 16 to both sides}
x = 7 {divided both sides by 2}


son is 7 years old now
