3x - x + 4 = 4(2x +1)

• x = -6

• x = 1

• x = 6

• x = 0

3(3x - 6) = 18

• x = 4

• x = -4

• x = 2

• x = -2

5x - 14 = 8x + 4

• x = 6

• x = -6

• x = -18/13

• x = 10/3

38 + 7k = 8(k + 4)

• x = 6

• x = 8

• x = -6

• x = 1

What is the first step in solving the equation 2a - 4(a - 5) = 10

Solve the equation:

3x - x + 4 = 4(2x +1)

• x = -1

• x = -6

• x = 6

• x = 0

Solve for x:

4 - 2(x - 3) = 24

• x = - 7

• x = 7

• x = 14

• x = - 14

6x + 3(-x + 11) = 3

• x = -10

• x = 10

• x = 15

• x = -15
