Question

Evaluate using the values given y-x-x; use x=5 and y=4

Answer 1

Given the expression:

`y-x-x`

First, you can simplify both x-terms:

`y-2x`

Replace the expression with the given values for y and x and solve

`\begin{gathered} y-2x=4-2\cdot5 \\ 4-10=-6 \end{gathered}`

The result of the expression when y=4 and x=5 is 6
