Solving One-Step Linear Equations
Some linear equations can be solved with a single operation. For this type of equation, use the inverse operation to solve.
Example 1:
Solve for .
The inverse operation of addition is subtraction. So, subtract from both sides.
Example 2:
Solve for .
The inverse operation of multiplication is division.
So, divide both sides by (which is the same as multiplying by ).
