use distribultive property and mltiply out 15 to 4c and -6
60c-90=5c-3
then subtract 5c from both sides
60c-90=5c-3
-5c -5c
55c-90=-3
add 90 to both sides
55c-90=-3
+90 +90
55c=87
divide by 55 on both sides
55c=87
/55 /55
c=87/55

distribute
so
60c-90=5c-3
so then we can add 90 to both sides
and subtract 5c from both sides to form
55c=87
divide both by 55 and
c=1.58
