Which operation is NOT appropriate to solve the following equation:
3y=17

• Subtract 2y from both sides
• Divide both sides by 3
• Multiply both sides by one third
• All three methods are appropriate

Which operation is appropriate to solve the following equation:
f² = 196

• Divide both sides by f
• Take the square root of both sides
• Divide both sides by 196
• More than one of these is fine

Which operation is NOT an appropriate step to solve the following equation:
5y + 3 = 17 - 2y

• Add 2y to both sides
• Subtract 3 from both sides
• Add 17 to both sides
• All three methods are appropriate
