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

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

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

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

Answer each question by selecting the proper alternative from those given below each question so as to make the statement true: The solution of the equations (x)/(a)+(y)/(b)=2 and ax-by=a^(2)-b^(2) is ……………. a) x = a , y = b b) x = −a , y = −b c) x = a , y = −b d) x = −a , y = b

The value of y which satisfies (x)/(a)=(y)/(b) and ax+by=a^(2)+b^(2) is

x+y=a+b,ax-by=a^(2)-b^(2)

If a circle passes through the point (a, b) and cuts the circle x^2 + y^2 = 4 orthogonally, then the locus of its centre is (a) 2ax+2by-(a^(2)+b^(2)+4)=0 (b) 2ax+2by-(a^(2)-b^(2)+k^(2))=0 (c) x^(2)+y^(2)-3ax-4by+(a^(2)+b^(2)-k^(2))=0 (d) x^(2)+y^(2)-2ax-3by+(a^(2)-b^(2)-k^(2))=0

Solve the following pair of linear equations by cross multiplication method : x/a + y/b -2 =0, ax-by= a^2-b^2 .

{:(x + y = a + b),(ax - by = a^(2) - b^(2)):}
