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 graph of the equation intersect the x-axis
C) write the points where the graph of the equation intersect the y-axis
D)

I would say D
e + 5 = 3e - 11 
3e - 11 = e + 5 
3e - e = 5 + 11 
2e = 16 
e = 16/2 
e = 8 
j = 8 + 5 
j = 13
because you find the value of e, substitute it into the equation and find j
