Question

If 13x + 15y = 41 and 15x + 13y = 43 then find the value of (X - Y )
​

Answer 1

Step-by-step explanation:

15x+13y=43 --eq1

13x+15y=41 -eq2

subtract eq2 from eq1

15x+13y-13x-15y= 43-41

2x-2y=2

2(x-y) =2

x-y=1

Answer 2

Answer:

-2

Step-by-step explanation:

3x+15y=114                              ...(i)

15x+13y=110                           ...(ii)

On subtracting (i) from (ii) , we get

2x−2y=−4

2(x-y)=-4

⇒x−y=−4/2=-2

Hope this helps!!
