Answer:14/3
Step-by-step explanation:
2(3x-4)=20
Divide both sides by2
2(3x-4)/2=20/2
3x-4=10
Add 4 to both sides
3x-4+4=10+4
3x=14
Divide both sides by 3
3x/3=14/3
x=14/3

Answer:
Allen sold 50 cell phones while Kay sold 67 cell phones.
Step-by-step explanation:
Let the number of cell phones sold by Allen be x. This will imply that the number of cell phones sold by Kay is x + 17.
Furthermore, we are informed that together they sold a total of 117 cell phones. Therefore, we use the following equation to determine the number of cell phones sold by each;
x + x + 17 = 117
2x + 17 = 117
2x = 100
x = 50
Therefore, Allen sold 50 cell phones while Kay sold 67 cell phones.
