Rachel is 11 years older than Scott. Rachel's age is 7 years less than two times Scott's age. The system below models the relationship between Rachel's age (r) and Scott's age (s):

r = s + 11
r = 2s – 7

Which is the correct method to find Rachel's and Scott's ages?

A. Solve r + 11 = 2r – 7 to find the value of s.
B. Solve s + 11 = 2s – 7 to find the value of s.
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.

Respuesta :

Answer:

B. Solve s + 11 = 2s – 7 to find the value of s.

B. we know that r equals both equations, and that r=r, so they should equal each other.
Hope this helps!
