No because there is no negative number being multiplied times a positive number
32 + 2x = 84
2x = 52
x = 26

Answer: the total number of coupon books sold is 20.
Step-by-step explanation:
Let x represent the number of coupon books that Mario sold.
Let y represent the number of coupon books that Luigi sold.
Apparently, Mario is a much better salesperson, because he sold 4 times as many coupon books as Luigi. This is expressed as
x = 4y
If Luigi sold 12 fewer coupon books than Mario, the expression would be
x = y + 12 - - - - - - - - - - -- -1
Substituting x = 4y into equation 1, it becomes
4y = y + 12
4y - y = 12
3y = 12
y = 12/3
y = 4
x = 4y = 4 × 4
x = 16
The total number of coupon books that the two boys sold is
4 + 16 = 20
Answer:
x = 9
y = 6
Step-by-step explanation:
- Divide 15 by 2: 15 ÷ 2 = 7.5
- Subtract 0.5 from 7.5 (this will later be added back): 7.5 - 0.5 = 7
- Subtract 1 from 7 (she wants to buy at least 2 more children books): 7 - 1 = 6
- Subtract 6 from 15 (6 being the number of puzzle books, 15 being the total number of items): 15 - 6 = 9 (number of children books)
