• k = 2

• k = 4

• k = -2

• k = -4

3 ( a + 22 ) = 12a + 30

• a = 8

• a = 2

• a = 4

Which step cannot be performed first when solving the equation

5 - 2(x - 7) = x + 1 + 3x

• Distributing -2 to (x - 7)

• Combining x and 3x

• 5 - 2

Solve for x:
5x - 14 = 8x + 4

• x = 6

• x = -6

• x = -18/13

• x = 10/3

Solve for x:

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

• x = -1

• x = 0

• x = -2

• x = 1

Solve for x:

3 ( a + 22 ) = 12a + 30

• a = 8

• a = 2

• a = 4

• a = -2

is 7 a solution to the equation
3x+8-x=5x-4

• yes

• no

• maybe

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

(a)  

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

• Add 4 to both sides

• Add the 2a and a 

• Distribute 4 to a and -5

• Distribute -4 to a and -5
