Answer      
Find out the  what is the sale price of the jeans including tax .
To prove
Let us assume that the sale price of the jeans including tax be x .
As given
Michael is buying a pair of jeans that regularly cost $40.
They are on sale for 20% off. 
If the tax rate is 8% .
20% is written in the decimal form

= 0.20
8% is written in the decimal form

= 0.08
Than the equation becomes
x = 40 - 40 × 0.20 + 40 × 0.08 
x = 40 - 8 + 3.2
x = 43.2 - 8
x = $35.2
Therefore the sale price of the jeans including tax be $ 35.2 .
 
        
             
        
        
        
Answer: 1. x=2
  2. x=5    
  3.x=-3
Isolate the variable by dividing each side by factors that don't contain the variable.
Move all terms not containing x    to the right side of the equation.
