Question 655731
cara is three times as old as madeline. in 10 years she will only be twice maddelines age how old was caras age 4 years ago
----
Equations:
c = 3m
c+10 = 2(m+10)
---
Substitute for "c" and solve for "m":
3m + 10 = 2m +20
m = 10 yrs (maddeline's age now)
---
m - 4 = 6 yrs (maddeline's age 4 yrs. ago)
