Solving Equations with Variables on Both Sides Lesson

Solving Equations with Variables on Both Sides Lesson

By the end of the lesson, you will be able to solve an equation that has variables on both sides of the equation.

​Solving Equations with Variables on Both Sides

• ​​Watch the video

• ​Record the examples and information on the notes page or in your notebook.

• ​Complete the "You Try" and check your work with Mrs. Jackson.

• ​Then, continue the rest of the lesson to get at least an 80%

Alternate method:

• Subtract 7x from both sides

- -13 = -10x - 33

• Add 33 to both sides

20 = -10x

• divide both sides by -10 and you still get x = -2
