a Define 2 variables to rep the amount of time ashley can spend on the two machines
b Write a system of 2 equations that describe the relationships between the amount of time ashley can spend on the 2 machines.
c. Solve the system of equations
d Interpret the solution

r = number of minutes on rowing machine
using our two conditions, we have:
s + r = 40
s = 2r
solve the system for s and r
