[2x-3y=8],[(x+y)/(x-y)=(7)/(3)]

If 2x+3y=34 and (x+y)/(y)=(13)/(8), then find the value of 5y+7x

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

Solve for x and y if [(x^(2)),(y^(2))]+2[(2x), (3y)]=3[(7),(-3)]

if (8x + l3y)/(8x - 13y) = (9)/(7) , find x : y .

Solve:(1)/(2(2x+3y))+(12)/(7(3x-2y))=(1)/(2)(7)/(2x+3y)+(4)/(3x-2y)=2 where 2x+3y!=0 and 3x-2y!=0

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

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

If [(x,x-y),(2x+y,7)]=[(3,1),(8,7)] write the value of y.

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
