36-4c-3c=22 i don't understand how to solve for c

Subtract 36 from both sides making it: -4c-3c=-14
Now subtract -4c and 3c making it: -7c=-14
Now divide by -7 on both sides making it: c=2
There you go

Add -4c and -3c to get -7c then subtract 36 from both sides so it's -7c=-14 then divide by -7 on each side to get c=2

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
