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
[tex]150=3x+60\\150-60=3x\\90=3x\\3x=90\\[/tex]
Dividing both sides by 3
[tex]\frac{3x}{3}=\frac{90}{3}\\x=30[/tex]
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.
