Answer:

0=0

This means it is true for all x

Step-by-step explanation:

-5 + 5 (x-7) = -40 + 5x

Step 1: 5x-40=-40+5x

Step 2: <em>Add 40 to both sides</em>

5x-40+40=-40+5x+40

Step 3: <em>Simplify</em>

5x=5x

Step 4: <em>Subtract 5x from both sides</em>

5x-5x=5x-5x

Step 5: <em>Simplify</em>

0=0

<em>Both sides are equal</em>

True

<em>Or</em>

True for all <em>x</em>
