Combining Like Terms Practice

Variable terms are called "variable" because:

• they are pretty.
• they never change.
• they vary (change).
• they don't have letters.

3x + 2x + 6y + 3
Which are like terms?

• 6y and 3
• 2x and 3
• 3x and 3
• 3x and 2x

3x + 3x + 3x - 3x - 3x - 3x - 3x =

• 0
• 3x
• -3x
• 6x

6x + 2y - 3x - y + 4y - 5y = 

• 3x 
• 9x + y
• 6x + y
• 3x + y

What are coefficients?

• The letters in an expression
• The numbers without a letter
• The same as constants
• The number before a letter 

What are the coefficients of the following expression?
3x + 4y + 6z + 3

• 3
• 3, 4, 6
• 4, 3
• 6, 4

Write a simplified expression for the picture.

• x + 2
• 2
• -2
• 3x - 2

Write a simplified expression for the picture.

• -4x + 3
• -4x
• 3x
• -3x + 3

3x + 2x + 5y =

• 5x + 5y
• 2x + 5y
• -5x + 5y
• 3x + 3y

Simplify:
1/2 x  +  3  + 1/3 y  + 1/2 x  + 1/3 y

• 1/3 y  + 1/2 x  + 3
• x + y + 3
• x + y 
• x + 2/3 y + 3
