solve the equation 8=c/-4+6

OpenStudy (anonymous):

In these problems, you must always isolate the variable you want to solve for. in this problem you can subtract 6 from both sides, which will get c more isolated:\[8-6=c/-4\]

OpenStudy (anonymous):

Now multiply both sides by (-4) to get c by itself: \[2(-4) = c = -8\]

thanks

Yup, remember that division always undoes multiplication. If you multiply (1/4) by 4 for example, you get 1. This is the same principle in these problems.
