Steps to Solve an Equation

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:
3(3x - 6) = 18

• x = 4

• x = -4

• no solution

• infinite solutions
