# How do you solve c-(-3)=100?

Jan 28, 2017

$c = 97$

#### Explanation:

Note that $- \left(- 3\right) = + 3$

$\Rightarrow c + 3 = 100 \leftarrow \text{ is equation to be solved}$

To solve for c, subtract 3 from both sides of the equation.

$c \cancel{+ 3} \cancel{- 3} = 100 - 3$

$\Rightarrow c = 97 \text{ is the solution}$
