Question

( a x+b y-a+b=0 quad x b )
( b x-a y-a-b=0 quad x a )
& ( a b x+b^{2} y-a b+b^{2}=0 )
( begin{aligned} a b x-a^{2} y-a^{2}-a b &=0 =&+quad+frac{1}{2} end{aligned} )
( left(a^{2}+b^{2}right) y+a^{2}+b^{2}=0 )
( therefore sqrt{y}=-1 )
( a x+b(-1)-a+b=0 )
( a x=a )
( x=1 )

# Find the values of r and y in the system of equations. ex + bv a+b=0 hx-ay-a-b=0
