# How do you solve 2x = 12?

Nov 26, 2015

$x = 6$

Another way of looking at it!

#### Explanation:

The you need to get one $x$ on its own on one side of = and everything else on the other side.

This is how you do it for your question:

When multiplying, change what you want to get rid of into 1 as anything multiplied by 1 does not change.

$\textcolor{b l u e}{\text{Method for getting rid of the 2 on the left.}}$

Divide both sides by 2

$\textcolor{b r o w n}{2 x} \div 2 = \textcolor{b r o w n}{12} \div 2$

$\textcolor{g r e e n}{\text{If you divide one side of = by any number you have to}}$
$\textcolor{g r e e n}{\text{divide the other side by the same number}}$

Write as: $\frac{2}{2} \times x = \frac{12}{2}$

but $\frac{2}{2}$ is 1

$1 \times x = 6$

$x = 6$
