[" 1."(ax)/(b)-(by)/(a)=a+b],[ax-by=2ab]quad " ICBSE "20091

Solve the following equations: (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

5. sin(ax+b)cos(ax+b)

Solve : (a)/(ax-1)+(b)/(bx-1)=a+b , where a+b ne 0, ab ne 0 .

sin (ax +b) cos (ax+b)

sin (ax +b) cos (ax+b)

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

sin (ax + b) cos (ax + b)

sin (ax + b) cos (ax + b)

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