This is what I got, hope it helps (I used a calculator for this on Google)

There are various ways in which to do this problem.  I'd suggest
converting 5 3/4 into an improper fraction and then dividing that improper fraction by 4:
20+3                              23          1       23
------- divided by 4 is   --------- * ----- = ------   (answer)
   4                                   4           4       16
        
             
        
        
        
In the step after -6x+10=4x+20, he moved the terms incorrectly. you have to add 6x to both sides so it would be 10=4x+6x+20 which simplifies to 10=10x+20. subtract 20 from both sides to get -10=10x. divide both sides by 10. the answer is x=-1
        
                    
             
        
        
        
X is equal to 2. The steps are listed below :)
 
        
             
        
        
        
Answer:
a = 6 or a = -58/8
Step-by-step explanation:
I think you meant to ask us to solve for a.
There are two cases to solve for:
5 + 8a = 53 or -(5 + 8a) = 53
8a = 48 or 5 + 8a = -53
a = 6 or 8a = -58
a = 6 or a = -58/8
