If x-y=6 and y=3, then find the value of x.

If x= -2 and y =3 , then find the value of (y/x)^y .

(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.

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)

If x-3y=2 and x+y=6 , then the values of x and y will be

If x^(2)+y^(2)=49 and x-y=3, then find the value of x^(3)-y^(3)

If 3x-2y=24 and 2x-3y=18, then find the value of x+y.

3x+y=19 and x+3y=1 then find the value of 2x+2y
