How do you solve these?
How do you solve these?
Combine like terms if you can (same side of the equal sign)
Get rid of addition or subtraction first if it's not being multiplied or divided by anything
Once the whole side of the equation is being multiplied or divided, get rid of divider (or multiplier)
Then, you should have a simple one or two step equation!
Let's do some examples:

Let's practice with a partner today!
With a partner, try the problems. As you work, take turns switching between the following roles:
With a partner, try the problems. As you work, take turns switching between the following roles:
Scribe - this partner is writing down each step using the vertical line method
Narrator - this partner is explaining out loud what is happening in each step and why
"Next, we will divide both sides by 6 because division is the opposite of multiplication."
"The first step is to draw a vertical line through the equals sign to separate the two halves of the equation."
