Solving Equations

100

What is the first step to solve this equation:  4n - 2n = 4 

What is subtract  4n-2n=2n 

200

 2n=4  is the next step is

What is divide 2 by both sides.

300

What would you do first  to solve this equation:   24 = 6(-x-3)   

What is distribute the 6 through the quantity.

400

The next step to solve this equation:   24 = -6x-18 

What is add 18 to both sides

500

The next step to solve this equation:   42=-6x 

What is divide both sides by -6
