" If "(x)/(4)+(y)/(3)=(5)/(12)" and "(x)/(2)+y=1," then the value of "(x+y)" is: "

If (x)/(4) + ( y)/(3) = (5)/(12) and (x)/(2) + y = 1 then find the value of (x + y ) .

If 3x+4y=12 and 4x+3y=9 , then find the value of x+y

If 3x+4y=12 and 4x+3y=9 , then find the value of x+y

Solve the pair of equations : (3)/(x) + (2)/(y) = 7 (5)/(x) - (4)/(y) = 13 Hence find the value of 27x - 12y .

If 3x+2y=12 and x y=6, find the value of 9x^2+4y^2

If x * y = x^2+y^2 then the value of (4 * 5) * 3 is

If 3x+2y=12 and x y=6 , find the value of 9x^2+4y^2
