What is the solution of the linear quadratic system or equations? y=x^2+5x-3 y-x=2

Because y=x+2, x^2+5x-3=x+2, therefore x^2+4x-5=0, so (x-1)(x+5), so x=-5,1

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

Where is the table?
