X²+Y²=250 and XY=117
What are the values of X and Y?

           x = -9,  y = -13    or    x = 13,   y = 9    or    x = -13,  y = -9    or     x = 9,   y = 13

Step-by-step explanation:

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
