Which of the following terms are alike?

5x            10              -3x            -16

2x²           0.2x            22              5y

What is:

5x, -3x and 0.2x

10, -16 and 22?

200

Simplify the expression by combining like terms:

-2x + 10 - 8x - 3

What is....-10x + 7?

300

Find the error, correct it and solve the equation:

-3x - 2 + 8 + 5x= 16

2x + 10 = 16

2x = 6

x = 3

What is 2x + 10 = 16

2x + 6 = 16

2x = 10

x = 5

400

Solve for x:

0.5x - 8 + 6.5x + 9 = 29

What is x = 4?

To The Left...To The Right

100

What should be your first step to solve the following equation and why?

What is subtract 4x from both sides of the equation?

200

Solve:

5x - 2 = 3x + 18?

What is x = 10?

300

Solve for x:

-8x + 12 = - 3x - 18

What is x = 6?

400

Solve:

10x - 2 = 4x

What is x = 1/3?

Inside Out
