Solving Equations with Variables on Both Sides
Steps…
 1.) Circle all terms with the variable
 2.) Decide if the variables are on the same side of the equal sign.
 If on the same side of the equal sign, combine like terms.
 If on different sides…
 3.) Decide which term is smaller.
 4.) Move the smaller term to the other side by dropping it down and changing the sign.
 5.) Solve as before.
Examples:
1.) 3x + 5 = 5x + 7
2.) 3x + 4 = -2x + 14
3.) 3x + 5 = 2x – 6
Try:
1.) 4x – 8 = -2x + 10
2.) 10x + 12 = 12x – 4
1.) Consecutive integers are integers that follow each other in order (for example 5, 6, 7). Find three
consecutive integers whose sum is 84.
2.) You have a 90-ound clad you are raising for a 4-H project. You expect the calf to gain 65 pounds
per month. In how many months will the animal weigh 1000 pounds?
3.) In any triangle, the sum of the measures of the angles is 180°. In triangle ABC, ‫ﮮ‬A is four times as
large as ‫ﮮ‬B. Angle C measures 20° less than ‫ﮮ‬B. Find the measure of each angle.
