4.07e Solving 1 Step Equations

4x = 44

• x = 40
• x = 11
• x = 48
• x = 176

y + 51 = 99

• 140

• 150

• 48

• Answer not Given

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

What is the inverse operation of multiplication?

• Addition
• Subtraction
• Division

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

• Inverse operations
• math
• variable
• PEMDAS

x - 4 = 17

• x = 21
• x = 13
• x = 19
• x = 24

x - 18 = 3

• x = 37
• x = 15
• x = -21
• x = 21

x + 24 = 44

• x = -20
• x = 68
• x = 20
• x = -68

To solve the equation
x + 5 = 8
 I would ....

• subtract 5 from x
• subtract 5 from both sides
• subtract 5 from one side and add 5 to the other
• add 5 to both sides

in 3a =12,
I would....

• add 3 to both sides
• subtract 3 from both sides
• divide both sides by 3
• divide just the right by 3
