It already is a decimal:)
Option B is your answer.
3/5x - 5 + 5/5x - 4 = - 1
8/5x - 9 = - 1
8/5x = - 1+ 9
8/5x = 8
Multiply both sides by 5/8 (the reciprocal of the coefficient) to isolate variable X.
(5/8)(8/5x) = 8(5/8)
x = 40/8
x = 5
X = No. of professors
x + 14x = 37,500
(No. of professors + 14 times the no. of professors = total)
Add.
15x = 37,500
Isolate x by eliminating 15.
15x/15 = 37,500/15
x = 2,500
There are 2,500 professors in the college.
37,500 - 2,500
(Total - no. of professors = no. of students)
= 35,000
There are 35,000 students in the college.
