What is the first step in solving a multi-step equation?

• Use substitution

• Solve for the unknown directly

• Add and subtract first

• Multiply and divide first

What is the first step in solving the equation 3x - 4 = 11?

• Divide both sides by 3

• Add 4 to both sides

• Subtract 4 from both sides

• Multiply both sides by 3

After adding 4 to both sides in the equation 3x - 4 = 11, what is the next step?

• Add 4 to both sides again

• Subtract 4 from both sides

• Multiply both sides by 3

• Divide both sides by 3

What is the final answer for x in the equation 3x = 15?

• x = -15

• x = 5

• x = -5

• x = 15

When solving the equation 2x - 3 = 9, what should you do first?

• Multiply both sides by 2

• Subtract 3 from both sides

• Add 3 to both sides

• Divide both sides by 2

After adding 3 to both sides in the equation 2x - 3 = 9, what is the next step?

• Divide both sides by 2

• Subtract 3 from both sides

• Multiply both sides by 2

• Add 3 to both sides again

In the equation 6x + 2 = 20, what operation should be performed first?

• Add 2 to both sides

• Subtract 2 from both sides

• Divide both sides by 6

• Multiply both sides by 6

What is the final step in solving the equation 6x = 18?

• Multiply both sides by 6
