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

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

If 2x+3y=14\ a n d\ 2x-3y=2, find the value of x y . [Hint use (2x+3y)^2-(2x-3y)^2=24 x y]

If 3x+2y=10 and 2x+3y=15 , find the value of x+y .

If 2x+3y=14 and 2x-3y=2, find the value of xy.[ Hint use (2x+3y)^(2)-(2x-3y)^(2)=24xy

If 3x + 5y = 21 and 2x +3y = 13 , then find the values of x and y .

If 3x + 2y = 10 and 2x + 3y = 15, find the value of x + y.
