Lesson 2.6 Solving for Variables Step by Step Solutions

To find the unknown, begin by isolating the term containing it. If the equation involves addition or subtraction, first eliminate constants from both sides. This will leave the term with the unknown on one side.

Next, address any multiplication or division. If the unknown is multiplied by a number, divide both sides by that number to get the unknown alone. Similarly, if the unknown is divided, multiply both sides by the divisor.

Be sure to check your result by substituting the value back into the original equation. This ensures that both sides are equal and confirms the solution is correct.
