Step-by-step explanation:
x=3 and y=2
Step-by-step explanation:
Given Equation:
\dfrac{5}{x+y}-\dfrac{2}{x-y}=-1x+y5−x−y2=−1
\dfrac{15}{x+y}+\dfrac{7}{x-y}=10x+y15+x−y7=10
\dfrac{1}{x+y}=ux+y1=u
\dfrac{1}{x-y}=vx−y1=v
Reducible linear equation
5u-2v=-15u−2v=−1
15u+7v=1015u+7v=10

Answer:
5/x+y-2/x-y=-1
5(x-y)-2(x+y)/(x+y)(x-y)=-1
5x-5y-2x-2y/x²-y²=-1
3x-7y/x²-y²=-1
3x-7y=-x²+y²
x²-y²+3x-7y=0
