Identifying Like Terms
Are 5x and 2y like terms?
No, they have different variables
3, x, and 8x are examples of what?
terms
Simplify by combining like terms
3x + 2x
5x
Simplify by using the distributive property
3(4x + 1)
12x + 3
Simplify by using the distributive property
13(x + 14)
3x - 182
Are 3 and -7 like terms?
Yes, they are terms without variables (CONSTANTS)
3, 5, 1.5, and -9 are examples of what?
constants
Simplify by combining like terms
4x - 2x + 1
2x + 1
Simplify by using the distributive property
5(3x - 10)
15x - 50
Simplify by using the distributive property
11(4 + 21x)
44 - 231
Are 4y and -4y like terms?
Yes, they have the same variable.
Letters used to represent numbers are called what?
variables
Simplify by combining like terms
-3y + 7y + 10 - 3

Simplify by using the distributive property
2(9x + 13.5)
18x - 27
Simplify using the distributive property
4(65y - 130)
260y + 520
Are -x and x like terms?
Yes, they have the same variable
The number in front of a variable in a term is called what?
a coefficient
Simplify by combining like terms
-10 - 5x + 14 - 6x

1
Simplify by combining like terms
-13x - 7 + 10 + 10x
-3x + 3
Simplify by using the distributive property
3(4x + 5.4)
12x + 16.2
