Exploring Variables on Both Sides in Equations

This video tutorial covers solving multi-step equations with variables on both sides. It begins with an introduction to the concept, followed by detailed steps on using the distributive property, handling negative coefficients, and solving equations that result in fractional solutions. The tutorial emphasizes combining like terms and isolating variables to find solutions.

What property is used first when solving equations with parentheses?

• Additive property

• Distributive property

• Associative property

• Commutative property

What operation is necessary to simplify the equation 9(x + 1/2) = 3(x + 11)?

• Addition

• Division

• Subtraction

• Multiplication

CCSS.8.EE.C.7B

After simplifying and distributing, what is the simplified form of the equation 9(x + 1/2) = 3(x + 11)?

• 9x + 1 = 3x + 33

• 9x + 1 = 6x + 22

• 9x + 0.5 = 3x + 11

• 18x + 2 = 6x + 22

What is the final value of x in the equation 9x + 1 = 6x + 22?

• x = 11/3

• x = 21

• x = 7

• x = 3

How do you isolate x in the equation 3x + 1 = 22?

• Add 1 to both sides

• Subtract 1 from both sides

• Divide both sides by 3

• Multiply both sides by 3
