what is the step to number 4?

Mr. Imperfecto teaches another math class.  This time he has 23 students take a test, the average score on which is an 87.  Mr. Imperfecto realizes he put the wrong grade in for a student.  He entered a 35, and the score should have been an 85.  To the nearest integer, what is the new class average?

Could you write out the solution or make it more clear. I can't read the work when it is a jumble of numbers. Thank you.

How do I obtain the B0 and B1 numbers in step 3?
