2.00 - 1.50 = 0.50
0.50 - 1.75 = -1.25
Solution: he owns $1.25
        
                    
             
        
        
        
<span>1/3(21-3a)=6-a
I simplified the equation to the form, which is simple to understand 
<span>1/3(21-3a)=6-a
Simplifying:
<span> + 0.333333333333*(21-3a)=6-a
Reorder the terms in parentheses
<span>+(+7-1a)=6-a
Remove unnecessary parentheses
<span>+7-1a=+6-a
We move all terms containing a to the left and all other terms to the right. 
<span>-1a+1a=+6-7
We simplify left and right side of the equation. 
<span>a=-1
<span>0=-1
The left and right sides are not equal, therefore there is no solution. This equation is invalid
Hope this helped
