In the equation 2x - 3 = x + 1, what is the first step to solve for x?

• Circle the terms.

• Add 3 to both sides.

• Divide both sides by 2.

• Subtract x from both sides.

What is the result when you combine positive and negative x terms in the equation 2x - 3 = x + 1?

• -x

• 0

• x

• 2x

What does it mean to isolate the variable in an equation?

• To add the same number to both sides.

• To get the variable alone on one side of the equation.

• To multiply both sides by the variable.

• To move all terms to one side.
