PLEASE HELP! SO CONFUSED!!
3.5(c-8)+c=12.5

Distribute 3.5 to c - 8.   3.5c - 28.  now add the extra one c. 4.5c - 28. now do the other stuff, starting with changing minus to a plus negative, so 3.5c + -28. now add 28 to 28 and 12.5 to get 30.5. Now divide 3.5 by 30.5. it should be 8.71 (If i am correct...)
