In this question, you're solving for x.
Solve for x:
2(4 - 8x) + 5(2x - 3) = 20 - 5x
Use the distributive property:
8 - 16x + 5(2x - 3) = 20 - 5x
8 - 16x + 10x - 15 = 20 - 5x
Combine like terms:
8 - 16x + 10x - 15 = 20 - 5x
8 - 6x - 15= 20 - 5x
-6x - 7 = 20 - 5x
Add 5x to both sides
-x - 7 = 20
Add 7 to both sides
-x = 27
Divide both sides by -1
x = -27
Answer:
x = -27

Step-by-step explanation:
Answer: the group rented 11 Person tubes and 4 cooler tubes
Step-by-step explanation:
There are two types of tubes, Person tube and cooler tube.
Let P represent number of Person tubes that the group rented.
Let C represent number of Cooler tubes that the group rented.
The group spends $270 to rent a total of 15 tubes and Person tube $20 Cooler tube $12.50. Two linear equations can be derived from the above information
P + C = 15 - - - - - - - 1
20P + 12.5C = 270 - - - -- - - 2
Substituting P = 15 - C into equation 2,
It becomes
20(15-C) + 12.5C = 270
300 - 20C + 12.5C = 270
- 20C + 12.5C = 270 -300
7.5C = - 30
C = 30/7.5 = 4
P = 15 - C
P = 15 - 4 = 11
Answer: the answer will be 24/15
