5x= 30

x = 6

200

x-6 =3

x = 9

300

6x -3 = 9

x = 2

400

x/5 + 3 = 10

x = 35

500

x/6 +9 = 10

x = 6

When x is on both sides of the =

100

Solve for x:

3x -12 = -5x +20

x = 4

200

Solve for x:

6x - 5 = -2x +35

x = 5

300

Solve for x:

-9x + 2 = -10x -30

x = -32

400

Solve for x:

5(2x +1) -6= 3(x -3)

x = -8/7

500

Solve for x:

3(4x +2) -8 = 2 (2x -3)

 x = -1/2

Absolute Value

100

|x|= 2

x = 2 and x = -2

200

|x-2| = -32

No Solution! Absolute value can't result in a negative.

300

|x| - 2 = 8

x = 10 and x = -10

400

|4x +1|= 9

x = 2 and x = -5/2

500

|x+4| +3 = 5

x =- 6 and x = -2
