Question 126618This question is from textbook Pre- Algebra
: I need to solve for C. Here is the equation:
9(2c + 5) + 3c = -75
Here is what I have done so far.
9 . 2c + 9.5 + 3c = -75
18c + 45 + 3c = -75
21c + 45 = -75
21c + 45 -45 = -75 + -75
I don't know where to go from here.
18c+45+3c=-75
- 3c -3c=-75
15c+45=-75
-45=-45
15c =-120
15 = 15 divide
c= -8
