Jamie is 5 years older than Ella. Jamie's age is 11 years less than three times Ella's age. The system below models the relationship between Jamie's age (j) and Ella's age (e):

j = e + 5
j = 3e − 11

Which of the following methods is correct to find Jamie's and Ella's age?

A) Solve j + 5 = 3j − 11 to find the value of j.
B) Write the points where the graphs of the equations intersect the x-axis.
C) Write the points where the graphs of the equations intersect the y-axis.
D) Solve e + 5 = 3e − 11 to find the value of e.

Answer is D:
e + 5 = 3e - 11

2e = 16
e = 8

Ella is 8 years old
Jamie is 8+5 = 13 years old
