Solving Two Step Equations: Key Concepts and Techniques

What is the first step in solving two-step equations?

• Isolate the variable

• Undo the constant

• Check the equation

• Undo the coefficient

In the equation 4x + 5 = 33, what operation is used to eliminate the constant?

• Multiplication

• Subtraction

• Addition

• Division

After subtracting 5 from both sides in the equation 4x + 5 = 33, what is the new equation?
