## Algebra: A Combined Approach (4th Edition)

$x = 30$
$2x = 60$ Step 1: is not needed because there is no fractions. $2x = 60$ Step 2: is not needed. $2x = 60$ Step 3: is not needed since no simplifying can be done on either side of the equation. $2x = 60$ Step 4: The equation is linear. $2x = 60$ 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. $2x = 60$ Step 6: Get the variable alone by using the multiplication property of equality. $2x \times \frac{1}{2} = 60 \times \frac{1}{2}$ $x = 30$ Final Step: Check each solution in the original equation. $2\times30 = 60$
