YOUR TURN:

Solve         3x + 8 = -7          *And check it!

Here's one with a bit of a twist:

Solve    6 - x - 6 = 7 - 6   which gives   -x = 1

 

Ditch the 6:

x isn't quite alone yet!
Multiply both sides by
-1:

(-1)(-x) = (1)(-1)  which gives   x = -1
 

OK, so what if there are x's on both sides?

9 - 3x = 5x + 6

Here's the game:

Get all x guys on one side and all number guys on the other.

*Ditch the smallest x guy first!  (Trust me.)
