Solving for a Variable
Combining Variables
Example 8
Solve 8x - 1 = 23 - 4x
Step 1. Use inverse functions to move like terms to the same side of the equation. Add 4x to both sides and simplify.
Step 2. Add 1 to both sides of the resulting equation and simplify.
Step 3. Divide both sides of the resulting equation by 12 and simplify.
Step 4. Check the solution.
