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? (4 points)

Solve j + 5 = 3j – 11 to find the value of j.

Write the points where the graphs of the equations intersect the x-axis.

Write the points where the graphs of the equations intersect the y-axis.

Solve e + 5 = 3e – 11 to find the value of e.

1. Solve e + 5 = 3 e – 11 to find the value of e

j = j

e + 5 = 3 e – 11

5 + 11 = 3 e - e

16 = 2 e

e = 8

j = e + 5 = 8 + 5 = 13

2. Clearly the 2nd version is correct
e + 5 = 3e – 11
16 = 2e
e = 8
then using j = e+5 = 8+5 = 13
Jamie is 13, Ella is 8

All conditions are met
