If `5x+y=19 and x-3y=7`, then x+y=

If x+y=19 and x-y=7, then xy= ?

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

If 7x+5y=-17 and 5x+7y=-19, then find the value of (i) x-y (ii) x+y.

IF 3x +5Y = 9 and 5x + 3y =7 then find the value of x+y

If 3x + 5y = 9 and 5x + 3y = 7 , then what is the value of x + y ?

If x+7y=15 and x+3y=7 , what is the value of x+5y?

3x+2y=5 2x-3y=7

If 5x+7y=17 , 7x+5y=19 then the value of x-y is ……….
