Variable x is 7 more than variable y. Variable x is also 1 less than y. Which of the following pairs of equations best models the relationship between x and y?

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?

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.
