a equals 2 1 / 2
a equals 2.5
5=15-24a/6

I simplify the equation to the form, which is simple to understand
5=15-24a/6

Simplifying:
5=15-4a

I moved all terms containing A to the left and all other terms to the right:
+4a=+15-5

Then i simplify the left and right side of the equation:
+4a=+10

Finally I divided both sides of the equation by 04 to get a:
a=2.5
