Question

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):

s = c + 7
s = 2c – 13

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


Solve s + 7 = 2s – 13 to find the value of s.
Solve c + 7 = 2c – 13 to find the value of c.
