Explanation:
While solving literal equations could be quite overwelhming, simply solve it by using normal equation solving methods.
For example, if you were to solve 2x + 3 = 9
You would add 3 on both sides and divide both sides by 2 to determine x.
Do the same thing for literal equations, and if in doubts, plug in numbers to check your work.
Step-by-step explanation:
For this problem, add c on both sides, we do this because we are aiming to eliminate the c from both sides.
a+c =2b
In order to find the value of b, divide both sides by 2, we do this because we want to get rid of the coefficient.
This should leave you with the answer of b=a/2 + c/2

- "Is" means "equals".
- When a problem simply says "a number," I replace it with a variable.
It is written out like this: .
