$x = 6$

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. $3\times6 = 18$
