# How do you simplify 6+5x-(-3x)?

Apr 22, 2016

$6 + 8 x$

#### Explanation:

Consider $- \left(- 3 x\right)$

This is the same as:$\text{ } \left(- 1\right) \times \left(- 1\right) \times \left(3 x\right)$

But $\text{ } \left(- 1\right) \times \left(- 1\right) = + 1$ giving

$\left(+ 1\right) \times \left(3 x\right) = + 3 x$
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Given:$\text{ } 6 + 5 x - \left(- 3 x\right)$

Write as: $\text{ } 6 + 5 x + 3 x$

$= 6 + 8 x$
