# How do you solve the equation M=(b+c)/2?

Dec 12, 2016

There is not only one unique solution. There are infinitely many solutions.

#### Explanation:

You can't solve this equation with one set of values because there are 3 variables. There are an infinite number of solutions,

For example $M = \frac{b + c}{2}$ could be $9 = \frac{15 + 3}{2}$

However, each variable can be the subject of the formula:

For example: $\text{ "b = 2M-c" or } c = 2 M - b$
