 $-3=x+5$  

What would be the best first step to solving the equation?

• add 3 to both sides

• subtract 5 from both sides

• add 5 to both sides

• subtract -5 from both sides

Solve for y in the following equation:

y ÷ 3 = 12

• 36

• -36

• 4

• -4

Simplify the following expression:

3 + 5x + 8 - 2x

• -3x² - 11

• 3x² + 11

• 11 - 3x

• 11 + 3x

Answer explanation

3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18

Simplify: x + 3x + 6x + x

• 9x

• 11x

• 2x + 9x

• Can't be simplified

3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18

Simplify the following expression by combining like terms:
3(2x - 4) + 6x - 1

• 12x - 13
• 12x - 5
• 11x - 2
• -x

Do I need to distribute, combine like terms, or both?

• Distribute

• Combine like terms

• Both

2x - 3 + 4x = 27

• 12
• 4
• 5
• 15

Simplify

5x² + 5y + 2x² + 4y² – 4x² + 2y² - 4y

• 3x² + 3xy + 6y

• 6y² + 2xy + 2x

• 7x² + 35x

• 3x² + 6y² + y
