Shiloh is 7 years older than Courtney. Shiloh's age is 13 years less than two times Courtney's age. The system below models the relationship between Shiloh's age (s) and Courtney's age (c):

Question

s = c + 7
s = 2c − 13

Which of the following methods is correct to find Shiloh's and Courtney's age? (4 points)

A. Solve s + 7 = 2s − 13 to find the value of s.

B. Solve c + 7 = 2c − 13 to find the value of c.

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

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

Answer 1

B. Solve c + 7 = 2c − 13 to find the value of c.

This will allow you to find Courtney's age, and then you can use the equation s = c + 7 to find Shiloh's age.
