Explanation:
15=e/0.5
We simplify the equation to the form, which is simple to understand
15=e/0.5
We move all terms containing e to the left and all other terms to the right.
-2e=-15
We simplify left and right side of the equation.
-2e=-15
We divide both sides of the equation by -02 to get e.
e=7.5
