Solve for x:

5x - 14 = 8x + 4x

• x = 6

• x = -18/13

• x = -6

• x = 10/3

10x + 9 = 4x - 9

• x = 0

• x = 3

• x = -3

• x = -18

8x - 8 = -4x + 16

• x = 8

• x = 16

• x = 24

• x = 2

7w + 5 = 3w - 15

• w = 5

• w = -2

• w = 2

• w = -5

-5k + 10 = -2k - 14

• k = 8

• k = -8

• k = 2

• k = -2

4x - 1 = 2x + 7

• 7

• 4

• 15

• 9

6x + 7 = 3x + 16

• 2

• 6

• 4

• 3

The goal of solving a one, two, or multi-step equations is to:

• Find the constant

• Find the coefficient

• Find the value of the variable

• Get rid of the variable
