Subtract

from both sides

Divide both sides by 7

solution

To complete the process of solving the equation, understand what changes from one line to the next.

Start at the top with the first and second lines.

In the first line, there are two like terms on the left side of the equation.

The first step is to combine them. This makes a single variable term on the left side of the equation.

The missing description is Combine like

terms.

Look at the second and third lines.

Subtract

from both sides

To find the missing term, subtract

from both sides of the equation.

–

The missing term is

Look at the third and fourth lines.

In the third line, the variable

only appears once. It is on the left side, but it is not isolated. (There is also a constant term.) Undo operations to isolate the variable.

The next step is to undo the addition. Subtract 3 from both sides to eliminate the constant term from the left side of the equation.

–

The missing description is Subtract 3 from both

sides.

Look at the fourth and fifth lines.

Divide both sides by 7

To find the missing term, divide both sides of the equation by 7.

The missing term is 1.
