One Step Equations Lesson

By the end of the lesson, you'll be able to solve an equation using inverse operations.

​One Step Equations Using Inverse Operations

• ​​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%

Adding and subtracting one step equations

You will add the opposite to each side and find the value of the integer. Let's try some!

Now lets solve multiplication and division one step equations.

Multiple Choice

What would be the best first step to solving the equation?
-3=x+5

• add 3 to both sides
• subtract 5 from both sides
• add 5 to both sides
• subtract -5 from both sides

Multiple Choice

1. What would be the best first step to solving the equation?

$$x\ +\ \frac{1}{2}\ =\ -3$$  

• add 3 to both sides

• add 1/2 to both sides

• subtract 3 both sides

• subtract 1/2 from both sides

Multiple Choice

2.  What would be the best first step to solving the equation in one step?

$$\frac{2}{3}x\ =\ -4$$  

• multiply both sides by 2/3 

• multiply both sides by 3

• divide both sides by 2/3

• subtract 2/3  from both sides

Multiple Choice

3. What would be the best first step to solving the equation in one step?

$$\frac{y}{-3\ }\ =\ -9$$  

• multiply both sides by 3

• add 3 to each side

• divide both sides by -3

• multiply both sides by -3

Multiple Choice

In the equation

x + 7 = 12

7 is being added to the variable, x. How should you show your work to isolate the variable and solve the equation?

• Subtract 7 from both sides. The solution is x = 5.

• Add 7 to both sides.

  The solution is x = 19.

• Multiply both sides by 7 The solution is x = 84.
