#### Answer

$x = 6$

#### Work Step by Step

$3x = 18$
Step 1:
is not needed because there is no fractions.
Step 2:
is not needed.
Step 3:
is not needed since no simplifying can be done on either side of the equation.
Step 4:
The equation is linear.
Step 5: Get all variable terms on one side and all numbers on the other side by using the addition property of equality.
Already done.
$3x = 18$
Step 6: Get the variable alone by using the multiplication property of equality.
$3x \times \frac{1}{3} = 18 \times \frac{1}{3}$
$x = 6$
Final Step: Check each solution in the original equation.
$3\times6 = 18$
