Choose the correct first step for this equation. \ 7x\ =\ 2x\ -\ 20 NOTE: We do not want to move the 7x to the right. We want to move the variables AWAY from the constant term (-20).

• Subtract 2x from both sides.

• Add 2x from both sides.

• Subtract 20 from 2x.

8v - 4(v + 8) = 8

• 2

• 10

• 4

Solve the equation
12x - 15 = 3(2x+3)

• x = 4

• x = -4

• x = 2

• x = -2

• Adding 14x to both sides of the equation.

  To get

  -7 = 17x + 2

• Adding 7 to both sides of the equation.

  To get

  -14x = 3x + 9

• Subtracting 2 from both sides of the equation. 

  To get

  14x - 9 = 3x

• Adding 3x to both sides of the equation.

  To get

  -11x - 7 = 2

What is the first step you should take to solve this problem?

1 + 4n - 6n = 1 - 8n

• subtract 8n to both sides

• multiply 6n to both sides

• combine the like terms 4n + -6n

• add 1 to both sides

What is the first step you should take to solve this problem?

-3(x - 2) = -8 +9b

• add 8 to both sides

• subtract 9b from both sides

• Distribute -3 to the x and -2

• add 2 to both sides
