Simplifying Variable ExpressionsSlide2
Vocabulary:Term- a number or the product of a number and variables
Constant- a term that has no variables
Like terms- have identical variable (has the same variable with the same exponent)

Combining Like Terms
When combining like terms add the coefficients and keep the variable the same. Slide8
Simplify 3y + y
1. What are the like terms?
3y and y
2. What are the coefficients of the like terms?
3 and 1
3. Add the coefficients and keep the
variable the same.
3y + 1y = 4y
4. Your answer:
3y + y = 4ySlide9
Simplify 3b – 4b + b
1. What are the like terms?
3b, -4b, b
2. What are the coefficients of the like terms?
3, -4, 1
3. Add the coefficients and keep the
variable the same.
3b + -4b + 1b =0
4. Your answer:
3b – 4b + b = 0Slide10
Simplify 7p - 3q + 2p - 8
1. What are the like terms?
7p and 2p
2. What are the coefficients of the like terms?
7, 2
3. Add the coefficients and keep the
variable the same.
7p + 2p = 9p
4. Your answer:
7p – 3q + 2p -8 = 9p – 3q - 8Slide11
