(1)/(2(3x+4y))+(1)/(5(2x-3y))=(1)/(4)quad ;quad (5)/((3x+4y))-(2)/((2x-3y))=-(3)/(2)

Solve the following simultaneous equations. (1)/(2(3x+4y))+(1)/(5(2x-3y))=(1)/(4) , (5)/((3x+4y)) - (2)/((2x-3y))=(3)/(2)

Solve the following simultaneous equations 1/(2(3x+4y)) + 1/(5(2x-3y))=1/4, 5/(3x+4y) - 2/(2x-3y) = -3/2

{:((1)/(2(x + 2y)) + (5)/(3(3x - 2y))=(-3)/(2)),((5)/(4(x + 2y)) - (3)/(5(3x - 2y)) = (61)/(60)):}

(3) 3x-2y=(5)/(2) (1)/(3)x+3y=-(4)/(3)

Solve : (1)/(2x)+(1)/(4y)-(1)/(3z)=(1)/(4),(1)/(x)=(1)/(3y),(1)/(x)-(1)/(5y)+(4)/(z)=2 (2)/(15)

3x-2y=(5)/(2),(1)/(3)x+3y=(-4)/(3)
