What is the first step in solving the following equation?
3x - 5 = 20

• multiply both sides by 5
• add 5 to both sides
• divide both sides by 5
• subtract both sides by 5

What is the first step to solve this equation?
3n - 4 = -2 + 2n 

• Add 2n to both sides of the equation

• Add 3n to both sides of the equation

• Subtract 2n from both sides of the equation

• Subtract 4 from both sides of the equation

Solve the equation:
3(x - 1) = 2x + 9

• x = 12
• no solution
• x = 10
• x = 6

Solve the equation:
3x - x + 2 = 4(2x - 1)

• infinite solutions
• x = 1
• x = -1
• no solution

8v - 4(v + 8) = 8

• 2
• 10
• 4
• -4 

2x - 3 + 4x = 27

• 12
• 4
• 5
• 15

2x + 3(5x - 7) = 47

• 1
• 2
• 3
• 4

5x - 4 + 2x = 3

• 1
• 2
• 3
• 4

3x + 2(4x - 4) = 3

• 4
• 3
• 2
• 1
