Answer:
3x+y=45......equation 1
x-y=20......equation 2
Explanation:
There are now two equations, solve them using elimination or substitution method
I'm not 100% sure this is correct but this is the way I had learned.

:
35 minutes (See proof below)
Explanation:
Given
Velocity = v = 0.99c
Time = ∆t =5 minutes
Lorentz Factor is the factor by which time, length, and relativistic mass change for an object while that object is moving and it is given as
y = 1/√(1 - v²/c²) where v = velocity = 0.99c and c = time constant = 1
So,
y = 1/√(1 - (0.99c)²/c²)
y = 1/√(1 - 0.9801c²/c²)
y = 1/√(1 - 0.9801)
y = 1/√0.0199
y = 7.088812050083359
Calculating her catnap;
Catnap Time = ∆t * y
= 5 minutes * 7.088812050083359
= 35.44406025041679 minutes
= 35 minutes ----- Approximated
