To Solve 2 Step equations, Consider what is Directly attached (closest) to the variable, and get rid of

the other number first.

You get rid of that number the same way we did for 1 step equations.

Multiple Choice

What is directly attached to the variable in:

$$3x+7=13$$  

• 3

• 7

• 13

Multiple Choice

If 3 is directly attached to the variable, what do you get rid of first?

$$3x+7=13$$  

• 3

• 7

• 13

Multiple Choice

How do you get rid of the 7?

$$3x+7=13$$  

• Add 7

• Subtract 7

• Multiply by 7

• Divide by 7

Multiple Choice

Now you have a 1 step equation! EASY!

What do you do to solve for x?

3x= 6

• Add 3

• Subtract 3

• Multiply by 3

• Divide by 3

Multiple Choice

When you divide by 3, your answer to 3x=6 will be:

• 2

• -2

• 18

• -18
