Number of scarves Tail could make = 4 7/8 ÷ 1 5/8
= 39/8 ÷ 13/8
7/9 would be irrational, I think.
From the second equation y=-1-x so we can write -2x²+3x-1=-1-x.
So -2x²+4x=0, 2x(-x+2)=0, therefore x=0 or 2 and the corresponding y values are -1 and -3.
We can write the answers as ordered pairs (0,-1) and (2,-3).
