Question 398133
Alex is 6 years older than Sara. Sixteen years ago, Alex was 1 1/2 times as old as Sara. How old are they now?
---------
Equations:
a = s+6
(a-16) = (3/2)(s-16)
-----
Substitute for "a" and solve for "s":
(s+6-16) = (3/2)(s-16)
2(s-10) = 3s-48
2s-20 = 3s-48
s = 28 (Sara's age now)
----------------------
Solve for "a":
a = s+6
a = 28+6
a = 34 (Alex's age now)
