3x+60=150 can be used to determine the number of days you read. Solving the equation determines that you have been reading for 30 days.

Step-by-step explanation:

Total pages = 150

Pages per days = 3

Pages left to read = 60

Let,

x be the number of days.

According to given statement;

Total pages = Pages per day*number of days + Pages left to read

$150=3x+60\\150-60=3x\\90=3x\\3x=90\\$

Dividing both sides by 3

$\frac{3x}{3}=\frac{90}{3}\\x=30$

3x+60=150 can be used to determine the number of days you read. Solving the equation determines that you have been reading for 30 days.
