Question

Solve for a: b − 2a = c

Answer 1

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

Explanation:

Solving for the variable
`a`, given that :

`b-2a=c`

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

`-2a=c-b`

Now, we can divide both sides of the equation by the coefficient of
`a`, which would be
`-2`:

`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)`
