Answer:

a=-(c-b)/(2)

Explanation:

Solving for the variable
, given that :

b-2a=c

We can first start start by subtracting
from both sides of the equation:

-2a=c-b

Now, we can divide both sides of the equation by the coefficient of
, which would be
:

a=(c)/(-2)-(b)/(-2)

Applying the fraction rule
$(a)/(c)\pm(b)/(c) =(a\pm b)/(c)$ :

a=(c-b)/(-2)

Then, apply the fraction rule
(a)/(-b) =-(a)/(b)

a=-(c-b)/(2)
