Question

X - y = 3 work out the value of y - x

Answer 1

The answer is y-x=-3
As x - y = 3
Transposing x to the right hand side = 3-x = -y
= transpose three to the other side you will get = -x = -y-3
And then transposing y to the other side will give you y-x = -3

Answer 2

Explanation:

If x-y =3 then y-x =-3

For example: 10-5 =5 / 5 - 10 =-5

Hope this helps..
