Question 995699
let m = Mother's a age
let s = son's
:
Write an equation for each statement
:
The mother is eight more than twice the age of her son.
m = 2s + 8
 Six years ago, she was four more than three times her son's age then.
m - 6 = 3(s - 6) + 4
m - 6 = 3s - 18 + 4
m = 3s - 18 + 6 + 4
m = 3s - 8
replace m with (2s+8) from the 1st statement
2s + 8 = 3s - 8
8 + 8 = 3s - 2s
16 = s
then
m = 2(16) + 8
m = 40
:
 How old are they now. Mom's 40, son's 16
