" (v) "[(ax)/(b)-(by)/(a)=a+b],[ax-by=2ab]

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

Solve the following equations: (ax)/(b)-(by)/(a)=a+b , ax-by=2ab.

(ax+b)^(2)

(ax +b)^(2)

(ax^(2)+ b/x)

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

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

Solve (x + ab)/(2) = (y + ab)/(2) and ax + by = a^(2) + b^(2) .

(ax + b)^(2)

If ax+by+c=0 " and " a'x+b'y+c'=0 , then prove that x/(bc'-b'c)=y/(ca'-c'a)=1/(ab'-a'b)
