Solve 1/4(20-4a)=6-a a. -1 b. 0 c. all real numbers d. no solution

1/4(20-4a)=6-a

We simplify the equation to the form, which is simple to understand  

1/4(20-4a)=6-a

Simplifying:

+ 0.25*(20-4a)=6-a

Reorder the terms in parentheses

+(+5-1a)=6-a

Remove unnecessary parentheses

+5-1a=+6-a

We move all terms containing a to the left and all other terms to the right.  

-1a+1a=+6-5

We simplify left and right side of the equation.  

a=+1

0=1

The left and right sides are not equal, therefore there is no solution. This equation is invalid.
