Question

Find the value of x - y, if 5x + 4y = 14 and 4x + 5y = 13​

Answer 1

hanging haha ninth time and hmmmm?!.

Answer 2

Answer:

x-y = 1

Step-by-step explanation:

5x + 4y = 14 (1)

And

4x + 5y = 13 (2)

Now multiply (1) by 5 and multiply (2) by 4 to solve for x

25x + 20y = 70 (3)

16x + 20y = 52 (4)

9x = 18 [ by subtracting (4) from (3) ]

x= 2

Substituting this in (1)

5(2) + 4y = 14

y= 14-10/4

y= 1

Therefore x-y = 2-1 = 1
