Which statement best describes the first step to the equation?

-11-3x=44-2x

• Add 3 to both sides

• Add 11 to both sides

• Get the variables on one side

• Add 2 to both sides

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.
