distribute the negative first -7c+18-2>0
simplify -7c+16>0
subtract 16 both sides -7c>-16
divide by -1
MOST IMPORTANT PART
when you divide both sides by -1, you HAVE to change the greater/less than sign
so -7c>-16 becomes 7c<16
now divide by 7
c<16/7
I hope you don't yet want to graph it, because graphing is something that's a bit harder to show here
