assessment on multi steps equations

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

2x - 3 + 4x = 27

• 12
• 4
• 5
• 15

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

• 4
• 3
• 2
• 1

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

• 4
• 3
• 2
• 1

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

• x = 1
• x = 2
• x = 3
• x = 4

8v - 4(v + 8) = 8

• 2
• 10
• 4
• -4 

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

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

Solve:
2(4x-3) - 8 = 4 + 2x

• x = 5/3
• x = 3
• x = 1
• x = 2

Solve the equation
12x - 15 = 3(2x+3)

• x = 4
• x = -4
• x = 2
• x = -2
