1.If `x/y=(3/2)^2 divide(5/7)^0`,find the value of `(y/x)^3`

If (x/y) = ( 3/2 )^-2 ÷ ( 3/7)^0 , find the value of (x/y)^-3

Find the value of x, if y=2x-3 and y=5

If 2x^(2)-7xy+3y^(2)=0, then find the value of x:y.

If 3x+5y =9 and 5x+3y=7, then find the value of x+y.

If ((2x-y)/(x+2y))=(1)/(2), then find the value of ((3x-y)/(3x+y))

If x:y=2:3, find the value of (3x+2y):(2x+5y)

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

(i) x+2y=-7 and 3x-2y=-1, then find the value of x. (ii) If x+y=8 and 4y-x=2, then find the value of y. (iii) If 3x+5y=9 and 5x+3y=7, then find the value of x+y. (iv) If 3x-y=11 and x-3y=17, then find the value of x-y.
