Betsey is 11 years older than Waldo. Betsey's age is 15 years less than three times Waldo's age. The system below models the relationship between Betsey's age (b) and Waldo's age (w):
b = w + 11
b = 3w − 15
Which of the following methods is correct to find Betsey's and Waldo's age?
Solve w + 11 = 3w − 15 to find the value of w.
Solve b + 11 = 3b − 15 to find the value of b.

Lets solve.
w+11=3w-15
2w=26
w=13
b=w+11
b=(13)+11=24
