Bell Work 12/16

Which of the following are basic rules used for solving algebraic equations?

• Whatever you do to one side of the equal sign, you must copy and do on the other side of the equal sign

• Always do the Inverse Operation on the side with out the variable

• Always do the Inverse operation on the side with the variable

• Just Subtract

What is the inverse operation of division?

• Subtraction

• Multiplication

• Division

• Addition

Solve for the variable (a) in the following equation:

32 = 8a

• a = 4

• a = 8

• a= 24

• a = 256

When you solve one-step equations, you can do anything you want to one side of the equal sign, as long as...

• it is mathematical
• you do the SAME thing to the other side
• solving equations is impossible
• I love Snow Days!

To solve one-step equations, you have to use the ________________ operation.

• Integer
• Inverse
• Additive
• Subtractive

-4x = 64

How should you show your work to isolate the variable and solve the equation?

• Subtract -4 from each side.

• Add -4 to each side.

• Multiply each side by -4.

• Divide both sides of the equation by -4.

2f + f

• 3f
• 2f
• f

Simplify the expression: 2x + 1 + 7x 

• 10x
• 10
• 9x + 1
• 9 + 1x

Simplify the expression: 7v + 2 + 12 + 2v

• 23
• 23v
• 9 + 14v
• 9v + 14

5a + 2a + 2a 

• 9a
