" (vi) "[(x)/(a)+(y)/(b)=a+b],[(x)/(a^(2))+(y)/(b^(2))=2,quad a,b!=0]

(x)/(a)+(y)/(b)=a+b(x)/(a^(2))+(y)/(b^(2))=2,a!=0,b!=0

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

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

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: (a^(2))/(x)-(b^(2))/(y)=0,quad (a^(2)b)/(x)+(b^(2)a)/(y)=a+b,quad x,y!=0

(a)/(x)-(b)/(y)=0,(ab^(2))/(x)+(a^(2)b)/(y)=a^(2)+b^(2)

2(x/a)+(y/b)=2; (x/a)-(y/b)=4

Solve (x)/(a) + (y)/(b) = 1 and a(x - a)- b(y + b) = 2a^(2) + b^(2) .
