One Step Equations and PEMDAS

Using the "opposite operation" to "undo" and isolate the variable when solving an equation is more commonly called...

• Inverse operations

• math

• variable

• PEMDAS

W + 32 =26

• W=58

• W=-58

• W=-6

• W=6

Why do you add 7 to both sides?

• To undo addition, you subtract.

• To balance the equation, you subtract 7 on both sides.

• To undo subtraction, you add.

• To balance the equation,you add 7 to both sides.

How do you solve this equation?

• add 21 to both sides

• add 6 to both sides

• subtract 21 from both sides

• subtract 6 from both sides

Solve the equation:
20.5 = x + 4

• 16.5

• 16.05

• 24.5

• 24.05

Solve the equation: z + 19 = 35

• z = 13

• z = 14

• z = 15

• z = 16

Solve the equation
1/4 + x = 7/8

• 1

• 6/7

• 5/8

• 2/3

Solve the equation. 
  z- 2⅓= 1⅔

• z= 4

• z= 3

• z= 2⅓

• z= 3⅔

What property states that you can add the same number to both sides of an equation and the two sides will remain equal.

• distributive property

• addition property of equality

• commutative property

• associative property

Solve the equation
x + 1¹/₂  = 5³/₄

• x = 4 ¹/₄

• x = 4 ⁵/₄

• x = 4 ²/₂

• x = 5
