What is a 2-step problem?

• An equation where 2 steps are needed to solve it.
• An equation where only one step is needed to solve it.
• A problem with only one operation present.
• A problem where you find the square-root of a number.

What is the first step in solving the equation?

• Add 4 to each side
• Subtract 4 from each side
• Subtract 2y from each side
• Divide each side by 2y

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.
