Question

Which of the following is not equivalent to x - y + z?
x + z - y
z + x - y
y - x + z
z - y + x

Answer 1

OK here

\(x-y+z\)

WE can see that x and z are positive and y is negative.

You can arrange terms and it will be still true.

But the fact that y is negative and other else is positive must remain true.

Answer 3

C
