[50*" solve for "x" and "y:],[(x)/(a)+(y)/(b)=a+b,(x)/(a^(2))+(y)/(b^(2))=2]

Solve: (x)/(a)+(y)/(b)=a+b(x)/(a^(2))+(y)/(b^(2))=2

Solve for xandy: (x)/(a)+(y)/(b)=2,ax-by=a^(2)-b^(2)

Solve the following pair of equations: (x)/(a)+ (y)/(b)= a +b, (x)/(a^(2)) + (y)/(b^(2))=2, a, b ne 0

Solve: (x)/(a)+(y)/(b)=a^(2)+b^(2) and (x)/(a^(2))+(y)/(b^(2))=a+b

Solve the following system of equations by method of cross-multiplication: (x)/(a)+(y)/(b)=a+b,quad (x)/(a^(2))+(y)/(b^(2))=2

Solve: x/a+y/b=a+b , x/(a^2)+y/(b^2)=2

Solve: (x)/(a)+(y)/(b)=2,quad ax-by=a^(2)-b^(2)

Solve for x and y:x^(2)-y^(2)=xy-ab,(x+y)(ax+by)=2ab(a+b)
