Her goal is to burn 335 calories during her routine. Write a system of equations that represents Megan's morning workout.

x = minutes of aerobics

y = minutes of stretching

x + y = 40

11x + 4y = 335

It is possible to solve those two equations for both x and y, but they are only are asking for the equations.

In case you are curious, x = 25
