Solve One Step Equation

What is the first step to solve this equation?

• add 5 to both sides

• subtract 5 from both sides

• divide both sides by 2

• divide both sides by -2

What does the equation look like after subtracting 5 from both sides?

• 2x = 14

• -2x = 14

• 2x = 4

• -2x = 4

Equation: - 2x = 4

What is the next step to solve the equation?

• add 2 to both sides

• subtract 2 from both sides

• divide both sides by 2

• divide both sides by -2

Equation: - 2x = 4

What does the equation look like after both sides are divided by -2?

• x = -2

• x = 2

• x = -8

• x = 8

Solve for "n".

Equation: y + 5y = -18

What is the first step to solve the equation?

• subtract y from both sides

• subtract y from 5y

• combine y + 5y

• subtract 5 from both sides

What does the equation look like after you combine y + 5y?

• 6y = -18

• 4y = -18

• 5y = - 19y

• 5y = -18

What is the next step to solve the equation?

• subtract 6 from both sides

• add 18 to both sides

• divide both sides by -18

• Divide both sides by 6

What does the equation look like after both sides are divided by 6?

• y = -3

• y = 3

• y = 12

• y = -12

What are the two equations?

• x - 4 = 6

  x - 4 = -6

• x - 4 = 6

  x + 4 = -6

• |x - 4| = 6

  |x - 4| = -6

• |x - 4| = 6

  |x + 4| = -6
