DETAILED EXPLANATION


Look at highlight_red%28+15+%29-a%2F3=-9.
Moved 15 to the right of expression
It becomes -a%2F3%2Bhighlight_green%28+15+%29=-9.

Look at -a%2F3%2B15=highlight_red%28+-9+%29.
Moved these terms to the left highlight_green%28+9+%29
It becomes -a%2F3%2B15%2Bhighlight_green%28+9+%29=0.

Look at -a%2F3%2Bhighlight_red%28+15+%29%2Bhighlight_red%28+9+%29=0.
Added fractions or integers together
It becomes -a%2F3%2Bhighlight_green%28+24+%29=0.

Look at highlight_red%28+-a%2F3%2B24+%29=0.
Solved linear equation highlight_red%28+-a%2F3%2B24=0+%29 equivalent to -0.333333333333333*a+24 =0
It becomes highlight_green%28+0+%29=0.
Result: 0=0
This is an equation! Solutions: a=72.

is that %2815-a%29%2F3+=+9 or 15+-+%28a%2F3%29+=+9??
The way you stated it, it is 15+-+%28a%2F3%29+=+9 so we'll solve that one
15+-+%28a%2F3%29+=+9
%2845+-+a%29%2F3+=+9
45+-+a+=+27
45+-+27+=+a
18+=+a
If the problem was %2815-a%29%2F3+=+9
Then
%2815-a%29%2F3+=+9
%2815-a%29+=+27
15-27+=+a
-12+=+a

15-a%2F3=-9

Step 1. Multiply three to both sides of the equation

3%2A15-3%2Aa%2F3=-9%2A3

45-a=-27

Step 2. Add a+27 to both sides

45-a%2Ba%2B27=-27%2Ba%2B27

a=72

Check...15-72%2F3=-9...which is a true statement.

Step 3. ANSWER is a=72

I hope the above steps were helpful.
