# How do you solve 3x-1=8?

Jun 28, 2015

The answer will be
$x = 3$

#### Explanation:

First, we will take the $- 1$ to the RHS. As it is negative, sending to RHS will make it positive. Therefore

$3 x = 8 + 1$
$3 x = 9$

Now we will send $3$ to the RHS. As $3$ is the multiple of $x$, sending it to RHS will make it a divisor.

$x = \frac{9}{3}$

Hence

$x = 3$
