Genevieve wants to verify that }(5x-20)-(4x-8) is equivalent to x. Which procedure can Genevieve follow to determine if

Gnom [1K]

They aren't equivalent

<h2>Explanation:</h2>

In order to determine whether the expression:

$(5x-20)-(4x-8)$

is equivalent to:

$x$

Genevieve needs to follow these steps:

Step 1. Get rid parentheses

$5x-20-4x+8$

Step 2. Combine like terms

$5x-4x-20+8$

Step 3. Solve

$x-12$

So:

$x\neq x-12$

Therefore, these two expressions aren't equivalent.
