Multistep Equations

100

What would you do first to solve this?

3(3x + 4) - 9 = 27

Distribute 

200

Solve: 

3x + 9x - 4x + 9 = 33 

x= 3

300

Solve.

2(x-5)=5x+23

x=-11

400

What is the goal of solving a multistep equation? 

To isolate the variable 

500

Solve:

x = 4 

True or False

100

True or False?

2x and 3y are the same term?

False

200

True or False?

The first step in a two-step equation is to add or subtract the constant?

Truuuuuueeeeeee

300

True or False?

The inverse of 3x is adding 3 to it?

False, you need to divide

400

True or False?

In x/4 = 8, x is equal to 2?

False, 

32 divided by 4 is equal to 8 so x = 32

500

True or False?

The number in front of the variable is called the Coanchors?

False it is called Coefficients
