Can you figure out what x is?

2(x + 2) + 2 = 8

Use the vertical line method, combining like terms, and the distributive property. What order do you need to solve this in?

Can you figure out what x is?

2(x + 2) = 6

Use the vertical line method and the distributive property!

I can solve equations involving the distributive property.

we've been working on basic one- and two-step equations. today, let's add another tool to our toolbox!

What's the difference between these two equations?

3(x - 1) = 12 3x - 1 = 12

In the one without parentheses, how do you solve it?

How about the one with parentheses?

Let's do some examples:

Does it help you most to watch me carefully, or to write these down along with me?

1. 2(x + 5) = 10

2. 3(x - 4) = 15

3. 4(2x + 1) = 12

4. 5(3x - 6) = 30

5. -3(x - 6) = -18

today, let's add something else:

What if there are constants OUTSIDE of the parentheses?

2(x + 1) - 3 = 3

Let's do some examples:

Does it help you most to watch me carefully, or to write these down along with me?

1. 2(x + 5) -3 = 13

2. -1 + 3(x - 4) = 14

Telepathy time!
