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

If 3x+5y=15 and x-2y=10 , what is the value of 2x+7y ?

If 17x -5y=8 and 14 x -7y =-7, what is the value of 3x + 2y ?

Choose the correct alternative answers for the following questions If 3x + 5y =9 and 5x + 3y= 7 , then what is the value of x + y ?

If 3x+5y=44 and 10x-2y=16 what is the value of x?

If 3x + 5y = 9 and 5x + 3y = 7 , then what is 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.
