1. Section 3.4
P. 154 - 157

2.  Some equations have variables on both sides.
To solve such equations, you will first collect
the variable terms on the side with the greater
variable coefficient.
 However, many students will find they like to
still bring the variables over to the left-hand
side of the equation.

3.  To get a “term” moved from one side to the
other, you will use the add/subt
transformation. You move a variable term the
same way you move a constant term – by
adding the opposite.
 64 – 12 x = 6x

4.  64 – 12 x = 6x
 64 – 12 x + 12x = 6x + 12x
Collect variables
64 + 0 = 18 x Simplify
64 = 18x
18 18 Division
32 = x Simplify
9

5. 17 – 2x = 6x + 9

6. 2/5(10x + 15) = 18 – 4(x – 3)

7. 3x – 6 + 5x = -10x + 30
