Answer:

Solving Linear Equations of One Variable or Literal Equations

• First, use the distributive property.

• Second, combine like terms on the same side of the equation.

• Third, combine like terms on opposite sides of the equation.

• Fourth, perform addition or subtraction on both sides of the equation.

• Fifth, perform multiplication or division on both sides of the equation.

• Lastly, check your answer by substituting your solution back into the original equation.

If the equation is in the form of a fraction equal to a number, multiply both sides by the denominator first.

Solving Linear Inequalities of One Variable

• Follow the same steps as for linear equations with one exception:

• If you multiply or divide both sides of the inequality by a negative number, you need to switch the direction of the inequality.
