# How do you simplify (3x+1/2)+(7x-4 1/2)?

Nov 17, 2016

$10 x - 4$

#### Explanation:

The brackets are not necessary at all because they are being added.

$3 x + \frac{1}{2} + 7 x - 4 \frac{1}{2} \text{ } \leftarrow$ re-arrange the terms

$= 3 x + 7 x + \frac{1}{2} - 4 \frac{1}{2} \text{ } \leftarrow \left(+ \frac{1}{2} - \frac{1}{2} = 0\right)$

$= 10 x - 4$
