Answer 3

Let's solve the equation:

720 - 640 + 20 = 5x

First, simplify the left side of the equation:

(720 - 640) + 20 = 80 + 20 = 100

So, the equation becomes:

100 = 5x

Now, divide both sides of the equation by 5 to isolate x:

100 / 5 = 5x / 5

20 = x

So, the solution to the equation is:

x = 20

Answer 4

To solve the equation 720 - 640 + 20 = 5x, you can follow these steps:

1. Start by simplifying the left side of the equation: 720 - 640 + 20 = 100 + 20 = 120

2. Now you have the equation: 120 = 5x

3. To isolate x, divide both sides of the equation by 5: (120 / 5) = (5x / 5)

4. Simplify: 24 = x

So, the solution to the equation is x = 24.
