$c = - 7$

#### Explanation:

First, lets walk through what each word/number means. Then we can set up an equation and solve.

• The word is is synonymous with equals, which is represented in an equation with the equal sign ($=$).

• In this problem, 10 can stay the way it is. There is nothing more to be done.

• More is another way to say "in addition" or "plus". We will display this in the equation using a plus sign ($+$).

• $c$ is a variable.

• 3 can be left alone.

So our equation would look like this:

$10 + c = 3$

Using basic math, we can solve this.

$c = 3 - 10$

$c = - 7$
