Solving Multi-Step Equations

What value for x makes the following equation true? 12x + 4x = 64

• x = 4

• x = 16

• x = 8

• x = -4

What is the first step to solve the following equation? 12x + 4x = 64

• Combine Like Terms

• Subtract 64 from both sides

• Divide both sides by 12

• Subtract 16 from both sides

Solve the following equation

5x + 3 = 28

• x = 25

• x - 6.2

• x = 5

• x = 3.8

When solving equations, you are "isolating" the variable. What does it mean to "isolate" the variable?

• To get the variable alone on one side of the equation?

• To remove the constant from one side of the equation, but leave the coefficient

• To remove the coefficient from one side of the equation, but leave the constant

• To have the variable equal zero

What is the first step you would do to solve this problem?

• Use the distributive property to remove the parentheses (multiply both terms inside the parentheses by 5)

• Combine like terms

• Subtract 5 from both sides

• Add 2 to both side

What is the first step you would do to solve this problem?

• Combine like terms

• Divide by 11 on both sides

• Subtract 11 from both sides

• Subtract m from both sides

What is the value for m that makes this equation true?

• 11

• 66

• 0

• 6

What is the value of x that makes this equation true?

• 0

• 3

• -3

• -15
