Multiple Choice

What is the first step in solving this equation:

2(n + 3) = 10

• Combining like terms on the left

• Combining like terms on the right

• Distributive Property

• Moving the variable term

• Moving the constant term

Multiple Choice

After distributive property, what will the equation be:

2(n + 3) = 10

• 6n + 6 = 10

• 2n + 6 = 20

• 2n + 3 = 10

• 2n + 6 = 10

Poll

Are there any terms to combine on the left side of the equation

2n + 6 = 10

• Yes

• No

Multiple Choice

Are there any terms on the right side to combine

2n + 6 = 10

• Yes

• No

Multiple Choice

To get the variable term by itself, what should you do

2n + 6 = 10

• Add 6 to both sides of the equation

• Subtract 6 from both sides of the equation

• Multiply by 6 on both sides of the equation

• Divide by 6 on both sides of the equation

Multiple Choice

Your equation now looks like this: 2n = 4

What should you do to find the answer?

• Add 2 to both sides of the equation

• Subtract 2 from both sides of the equation

• Multiply each side by 2

• Divide each side by 2

Multiple Choice

What should you do first when solving the equation

2(x - 2) + 28 = 2(2x +1)

• Combine like terms on the left

• Combine like terms on the right

• Distributive Property

• Solve for x

Solve

2(x - 2) + 28 = 2(2x +1)

Solve:

5(x + 4) = 2x + 20 + 2x

Solve:

x + 4(x - 2) = -1
