Peter is reading a 193-page book. He has read three pages more than one-fourth of the number of pages he hasn’t yet read. How many pages has he not yet read?
Let X be amount of pages that he has NOT yet read. So he read (x/4+3) pages Book has 193 pages. This means that x+(x/4+3)=193 x+(x/4+3)=193 5x/4+3=193 5x/4=190 x=190*4/5 x=152 pages he hasn't read yet
