First off, how many pages did Kendrick read? 8. How many days does Kendrick have left until he needs to have read 350 pages? 6. Using those facts, write an equation; 8 + 6p = 350.
To solve that equation, first subtract 8 from 350 to get 342. Doing this will isolate the variable, which is 6p. You will end up with this; 6p = 342. With this equation, divide both sides of the equation by 6.
In conclusion, your final answer should be 57 pages.
