Step-by-step explanation:  Given that Andre and Elena are reading a book in summer time. Andre read one-fifth of the book and Elena read 20 pages more than Andre. We are to find the total number of pages in the book if Elena is on page 55.

Let, 'x' be the total number of pages in the book. Then, according to the given information, we have

Thus, there are 175 pages in the book that Andre and Elena are reading.

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)
