# How do you solve 12x + 3 = 6x + 3?

Mar 31, 2018

$x = 0$

#### Explanation:

Push all the variables to one side and constants to the other.

We get $12 x - 6 x = 3 - 3$

$6 x = 0$

So, $x = 0$

color(magenta)(x=0

#### Explanation:

$12 x + 3 = 6 x + 3$

$12 x - 6 x = 3 - 3$

$6 x = 0$

$x = \frac{0}{6}$

color(magenta)(x=0

As a check:

$12 x + 3 = 6 x + 3$

$12 \left(0\right) + 3 = 6 \left(0\right) + 3$

$0 + 3 = 0 + 3$

color(red)(3=3

Hence it is proved that $x = 0$
