# How do you solve 2x + 4 = 6 ?

Nov 17, 2015

$x = 1$.

#### Explanation:

$2 x + 4 = 6$. We have to leave $x$ alone. So:
1. We pass the $4$ form the left, where it is adding ($+ 4$) to the right, where it will be doing the opposite, so, subtracting:
$2 x = 6 - 4$,
$2 x = 2$.
2. Now, we pass the $2$ from the left, where it is multiplying ($2 x$ is the same as $2 \cdot x$) to the right, were it will do the opposite, dividing:
$x = \frac{2}{2}$,
$x = 1$.
