General Strategy for Solving Linear Equations
- Simplify each side of the equation as much as possible.
Use the Distributive Property to remove any parentheses.
Combine like terms.
- Collect all the variable terms on one side of the equation.
Use the Addition or Subtraction Property of Equality.
- Collect all the constant terms on the other side of the equation.
Use the Addition or Subtraction Property of Equality.
- Make the coefficient of the variable term to equal to 1.
Use the Multiplication or Division Property of Equality.
State the solution to the equation.
- Check the solution.
Substitute the solution into the original equation.
