# How do you solve 2x+7=-7+x+6-x?

Jun 21, 2018

$x = - 4$

#### Explanation:

$2 x + 7 = - 7 + x + 6 - x$

Combine like terms on the right hand side of the equation:
$2 x + 7 = - 1$

Subtract $\textcolor{b l u e}{7}$ from both sides:
$2 x + 7 \quad \textcolor{b l u e}{- \quad 7} = - 1 \quad \textcolor{b l u e}{- \quad 7}$

$2 x = - 8$

Divide both sides by $\textcolor{b l u e}{2}$:
$\frac{2 x}{\textcolor{b l u e}{2}} = \frac{- 8}{\textcolor{b l u e}{2}}$

Therefore,
$x = - 4$

Hope this helps!

$x = - 4$

#### Explanation:

It's a simple addition and subtraction problem all you have to do is to get the numbers on a side and terms containing $x$ on the other side

$2 x + 7 = - 7 + x + 6 - x$

$2 x + 7 = - 7 + 6 \cancel{+ x - x}$

$2 x + 7 = - 1$

Subtract $7$ from both sides

$2 x \cancel{+ 7 - 7} = - 1 - 7$

$2 x = - 8$

Divide both sides by $2$

$x = - 4$
