4x - 5y + 20 = 0
<u>             - 20  - 20</u>
        4x - 5y = -20
 4x - 4x - 5y = -20 - 4x
              -5y = -20 - 4x
              <u>-5y</u> = <u>-4x - 20</u>
               -5         -5
                 y = ⁴/₅x + 4
The slope would be ⁴/₅.

Step-by-step explanation:
<u>Step 1: Define</u>
6(x - 2) = 36
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide 6 on both sides:                     x - 2 = 6
- Add 2 on both sides:                         x = 8
 
        
             
        
        
        
Step-by-step explanation:
Let x = number of games that Alex played 
The total money that he spent C is given by
 
 
If he spent $45, then we can write

Solving for x, we get

This means that Alex played 15 games.
