Example 1. Subtracting Expressions a. Subtract: (40 + 9) – (30 + 2). Answer: The opposite of a sum is the sum of its opposites. Order of operations

40 + 9 + (- (30 + 2)) 40 + 9 + (- 30) + (- 2) 49 + (- 30) + (- 2) 19 + (- 2) 17

(40 + 9)- (30 + 2) (49)- (32) 17

b. Subtract: (3x + 5y – 4) – (4x + 11). Answer: 3x + 5y + ( – 4) + ( – (4x + 11)) Subtraction as adding the opposite 3x + 5y + ( – 4) + ( – 4x) + ( – 11) The opposite of a sum is the sum of its opposites. 3x + ( – 4x) + 5y + ( – 4) + ( – 11) Any order, any grouping – x + 5y + ( – 15) Combining like terms – x + 5y – 15 Subtraction replaces adding the opposite. Have students check the equivalency of the expressions by substituting 2 for x and 6 for y. (3x + 5y – 4) – (4x + 11) (3(2) + 5(6) – 4) – (4(2) + 11) (6 + 30 – 4) – (8 + 11) (36 – 4) – (19) 32 – 19 13 – x + 5y – 15 – (2) + 5(6) – 15 – 2 + 30 + ( – 15) 28 + ( – 15) 13 → When writing the difference as adding the expression’s opposite in Example 1(b), what happens to the grouped terms that are being subtracted? → When the subtraction is changed to addition, every term in the parentheses that follows must be converted to its opposite.

Example 3. Using Expressions to Solve Problems A stick is x meters long. A string is 4 times as long as the stick. a. Express the length of the string in terms of x. Answer: The length of the stick in meters is x meters, so the string is 4∙x, or 4x, meters long.

b. If the total length of the string and the stick is 15 meters long, how long is the string? Answer: The length of the stick and the string together in meters can be represented by x + 4x, or 5x. If the length of the stick and string together is 15 meters, the length of the stick is 3 meters, and the length of the string is 12 meters.

Example 4. Expressions from Word Problems It costs Margo a processing fee of $3 to rent a storage unit, plus $17 per month to keep her belongings in the unit. Her friend Carissa wants to store a box of her belongings in Margo’s storage unit and tells her that she will pay her $1 toward the processing fee and $3 for every month that she keeps the box in storage. Write an expression in standard form that represents how much Margo will have to pay for the storage unit if Carissa contributes. Then, determine how much Margo will pay if she uses the storage unit for 6 months. Answer: Let m represent the number of months that the storage unit is rented. (17m + 3) – (3m + 1) Original expression 17m + 3 + ( – (3m + 1)) Subtraction as adding the opposite 17m + 3 + ( – 3m) + ( – 1) The opposite of the sum is the sum of its opposites. 17m + ( – 3m) + 3 + ( – 1) Any order, any grouping 14m + 2 Combined like terms This means that Margo will have to pay only $2 of the processing fee and $14 per month that the storage unit is used. 14(6) + 2 84 + 2 86 Margo will pay $86 toward the storage unit rental for 6 months of use.

Question 6. Marty and Stewart are stuffing envelopes with index cards. They are putting x index cards in each envelope. When they are finished, Marty has 15 stuffed envelopes and 4 extra index cards, and Stewart has 12 stuffed envelopes and 6 extra index cards. Write an expression in standard form that represents the number of index cards the boys started with. Explain what your expression means. Answer: They inserted the same number of index cards in each envelope, but that number is unknown, x. An expression that represents Marty’s index cards is 15x + 4 because he had 15 envelopes and 4 cards left over. An expression that represents Stewart’s index cards is 12x + 6 because he had 12 envelopes and 6 left over cards. Their total number of cards together would be: 15x + 4 + 12x + 6 15x + 12x + 4 + 6 27x + 10 This means that altogether, they have 27 envelopes with x index cards in each, plus another 10 leftover index cards.
