Two-Step Equations with Integers Mastery

What is the main difference between one-step and two-step equations?

• Two-step equations do not involve multiplication.

• Two-step equations require isolating the variable in two steps.

• One-step equations involve only addition.

• One-step equations are always easier.

In problem 1, what is the first step to isolate the variable r?

• Multiply both sides by 10.

• Divide both sides by 10.

• Add 4 to both sides.

• Subtract 4 from both sides.

For problem 2, what is the value of n when the equation is solved?

• -4

• 4

• -2

• 2

In problem 3, what operation is performed after moving -2 to the other side?

• Add 3 to both sides.

• Multiply both sides by 3.

• Divide both sides by 3.

• Subtract 3 from both sides.

What is the solution for r in problem 4?

• 1

• -1

• 6

• -6

In problem 6, what is the first step to solve the equation?

• Add 5 to both sides.

• Multiply both sides by 2.

• Divide both sides by 2.

• Subtract 5 from both sides.

What is the value of k in problem 10?

• 10
