<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

last one is the solution u should choose
X=3 or -3/4.<span>Îmi pare rău că nu mi-am arătat munca</span>
7 hours a day
7 x €9.20 = €
64.4 per day
6 days a week
€64.4 x 6 = €386.4 per week
Will:Mum = 5:2
386.4 / 7 =
55.2
Will: 55.2 x 5
= 276
After shares
his wages, Will makes $276 a week
<span>1932 / 276 = 7
weeks</span>
