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 relation
ship 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.
2 answers:
The correct method is to use the equation
e + 5 = 3e - 11
on solving, we get e = 8 and j = 13
Other methods are complicated.
The correct answer is to solve e+5=3e-11 for e.
