Question 442
<font face = "courier new" size = 3>
If Leah is 6 years older than her sister, Sue,  and John
is 5 years older than Leah, and the total of their ages is
41. Then how old is Sue?
`
>>...Leah is 6 years older than...Sue,...<<
<b>
Translation: L = S + 6
</b>
>>...John is 5 years older than Leah...<<
<b>
Translation: J = L + 5
</b>
>>...and the total of their ages is 41...<<
<b>
Translation L + S + J = 41
`
So you have the system:
`
L = S + 6
J = L + 5
L + S + J = 41
`
Can you solve this syetem?  If not post again:
`
 L - S ` ` = 6
-L ` ` + J = 5
 L + S + J = 41
`
Leah's age = L = 14, Sue's age = S = 8, John's age = J = 19
