Solving Two step equations with combining like terms

The main thing you have to remember is whatever you do to one side of the equation, you must do to the other side to keep the equation true.

-6 - 3y = 27

 

Add 6 to both sides. The 6 on the left side goes away when you add 6.

-3y = 27 + 6

 

-3y = 33

 

Divide both sides by -3. The -3 on the left side goes away when you divide by -3.

y = 33/(-3)

 

y = -11         Now it is solved for y. :)
