Question

The expression x-y equals 0.7 if x and y have certain values. Evaluate the following expression with the same values of x and y

y-x

Answer 1

-0.7

Explanation:

Given x - y = 0.7

We will assign x and y random values that has a difference of 0.7

x = 1.3

y = 0.6

Using these 2 values,

y-x = 0.6-1.3

= -0.7

As you can see here , you will get a reversed value when you reverse the expression.
