Question 690322
 Brad is eight more than two times as old as Sarah. In 10 years the sum of their ages withh be 76. How old is Sarah now?
---------
Equations:
b = 2s + 8
b+10  + s + 10 = 76
-----
Substitute for "b" and solve for "s":
2s+8 + 10 + s+10 = 76
3s + 28 = 76
3s = 48
s = 16 yrs (Sarah's age now)
----
Solve for "b":
b = 2s + 8
Brad = 40 yrs (Brad's age now)
----------
Cheers,
Stan H.
