Solving Two-Step Equations

The video tutorial from Brenes Math Club covers solving two-step equations. It begins with an introduction to the topic and explains the concept of reverse operations, which involves performing the opposite mathematical operation to isolate the variable. Two examples are provided: solving 4x + 8 = 24 and 1/3x - 2 = 16, with detailed steps for each. The video concludes with a reminder to check solutions by substitution and offers additional resources for practice.

What is the first step in solving a two-step equation?

• Multiply both sides by 2

• Add 5 to both sides

• Divide both sides by 3

• Perform the reverse operation

If an equation involves addition, what should you do to solve it?

• Add the same number to both sides

• Subtract the same number from both sides

• Divide both sides by the same number

• Multiply both sides by the same number

In the equation 4x + 8 = 24, what is the first operation you should perform?

• Multiply both sides by 4

• Subtract 8 from both sides

• Add 8 to both sides

• Divide both sides by 4

After subtracting 8 from both sides in the equation 4x + 8 = 24, what is the next step?

• Subtract 4 from both sides

• Add 4 to both sides

• Divide both sides by 4

• Multiply both sides by 4

How can you verify the solution of an equation?

• By guessing the value of x

• By adding random numbers to both sides

• By multiplying both sides by a random number

• By substituting the value of x back into the equation

In the equation 1/3x - 2 = 16, what is the first operation you should perform?

• Divide both sides by 3

• Subtract 2 from both sides

• Add 2 to both sides

• Multiply both sides by 3

What is the reciprocal of 1/3?

• 1/3

• 3/1

• 1/2

• 2/1

After finding the reciprocal of 1/3, what should you do next in the equation 1/3x = 18?

• Multiply both sides by 3

• Divide both sides by 3

• Subtract 3 from both sides

• Add 3 to both sides

How can you check if your solution for x is correct in the equation 1/3x - 2 = 16?

• By substituting x back into the equation

• By multiplying both sides by 2

• By dividing both sides by 2

• By adding 2 to both sides
