4. a musician's first album sells 234,499 copies the first
week it was released. during the second week, another
432,112 albums were sold. how many more albums
were sold during the second week than the first week?

Step-by-step explanation:

Let

x -----> the number of copies sold the first week

y ----> the number of copies sold the second week

we know that

To find out how many more albums  were sold during the second week than the first week, subtract the number of copies sold the first week from the number of copies sold the second week

y-x

we have

substitute

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
