[" 8."2x-(3y)/(4)=3],[" 5"x=2y+7]

2x - ( 3y)/(4) = 3 , 5x = 2y + 7 .

Solve : (7 + x)/(5) - (2x - y)/(4) = 3y - 5 (5y - 7)/(2) + (4x - 3)/(6) = 18 - 5x

If ( 2x - 3y + 1)/(2) = (x + 4y + 8)/(3) = ( 4x - 7y + 2)/(5) then what is (x +y) equal to ?

Solve by cross-multiplication method. (i) 8x-3y=12,5x=2y +7 (ii) 6x+ 7y -11 =0, 5x+ 2y =13 (iii) (2)/(x)+(3)/(y) =5, (3)/(x) -(1)/(y) +9=0

3x-4y=-7,5x-2y=0

2x+3y=8,4x+(3)/(2)y=7

If x=5 and y=-2 , then find the value of (i) (8x-2y+5)/(2x+4ty+12) " "(ii) (5x-6y-7)/(3x+6y+12)

Simplify: (2x+3y)(3x+4y)-(7x+3y)(x+2y)

Simplify: (2x+3y)(3x4y)-(7x+3y)(x+2y)
