Solving Two-Step Equations Challenge

What is a variable in the context of equations?

• A number that is added to both sides of the equation

• A number that is subtracted from both sides of the equation

• A placeholder for any number, usually represented by a letter

• A number that does not change

Which of the following is an example of a constant?

• x

• 75h

• 425

• h

In Melody's CD recording problem, what does the 75h represent?

• The number of hours

• The cost per hour

• The total cost

• The flat fee

What is the first step in solving the equation 75h + 425 = 8000?

• Divide both sides by 75

• Subtract 425 from both sides

• Add 425 to both sides

• Multiply both sides by 75

After subtracting 425 from both sides of the equation 75h + 425 = 8000, what is the next step?

• Divide both sides by 75

• Subtract 75 from both sides

• Add 425 to both sides

• Multiply both sides by 75

What is the solution to the equation 12n + 6 = 78?

• n = 6

• n = 9

• n = 8

• n = 7

In the equation 3x - 5 = 16, what is the value of x?

• x = 8

• x = 7

• x = 6

• x = 5

What is the result of solving the equation -8 = 2x + 4?

• x = -6

• x = -4

• x = -8

• x = -12

In the equation 2y - 3 = -9, what is the value of y?

• y = -3

• y = -4

• y = -5

• y = -6

What should you always do to keep an equation balanced?

• Whatever you do to one side, do to the other side

• Multiply both sides by the same number

• Subtract the same number from both sides

• Add the same number to both sides
