put this solution on YOUR website!Mrs. Shieh was 24 years old when Ingred was born. In three years the sum of their ages will be 68 years. How old is each now?
:
We can say that S is 24 yrs older than I, therefore
S = (I+24)
:
An equation for the statement:
"In three years the sum of their ages will be 68 years."
(S+3) + (I+3) = 68
S + I + 6 = 68
S + I = 68-6
S + I = 62
:
How old is each now?
:
Substitute (I+24) for S in the above equation
(I+24) + I = 62
2I = 62 - 24
I =
I = 19 yrs
then
19+24 = 43 yrs is S

Check solution in the statement:
"In three years the sum of their ages will be 68 years."
(43+3) + (19+3) = 68
