We know that the equation
is a true equation for a particular value of x.
Now, let's see what happens if we divide everything by 4. In other words:

Divide:

So, we get
.
When we divided everything by 4, we used the division property of equality. Under this property, the equation remains the same even if we divided since we did the <em>same thing to both sides of the equation. </em>
Therefore,
is also true for the same value of x because it is just a simplified version of
.
