We will use linear equation 10x+115=305 to solve this question, it will take 19 days to complete the book.
what is linear equation?
Linear equation is the equation where highest power of the variable used in the equation is 1. i.e. ax+b=0 where highest power of the variable x is 1.
Accoerding to this asked question,
the reader has already read 115 pages of the book.
Let she will take x days in order to finsh the remaining pages.
She reads 10 pages in one day.
So no. of pages she will read in x days = 10x
As she has read 115 pages, no. of pages she will cover from the book = 10x+115
According to asked question,
She has to finish the book in x days. so linear equation will be
10x+115=305
⇒10x=305-115
⇒10x=190
⇒x=19
It will take 19 days to complete the book.
