Best ResponseYou've already chosen the best response.0Shiloh 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? Solve s + 7 = 2s − 13 to find the value of s. Solve c + 7 = 2c − 13 to find the value of c. Write the points where the graphs of the equations intersect the xaxis. Write the points where the graphs of the equations intersect the yaxis.
