john read the first 114 pages of a novel which is 3 pages less than 1/3 of the novel. write the equation

tatyana61 [14]

The equation is:

$114=\frac{p}{3}-3$

And

Total number of pages are 351

Step-by-step explanation:

The equation has to be formed by using the given information.

Let p be the total number of pages in the novel

Then

1/3rd of the p will pe:

$\frac{p}{3}$

Total pages read by John = 114

Then according to the statement

$114=\frac{p}{3}-3$

We can solve the equation to get the total pages of the novel

$114=\frac{p}{3}-3\\Adding\ 3\ on\ both\ sides\\114+3=\frac{p}{3}-3+3\\117=\frac{p}{3}\\Multiplying\ both\ sides\ by\ 3\\3*117 = \frac{p}{3}*3\\p=351$

The equation is:

$114=\frac{p}{3}-3$

And

Total number of pages are 351
