Angle B and angle C are supplementary. If the measure of angle B is 14 times the measure of angle C, which equation can be used to find the measure of angle C?

-14x+x=180
-14x=90
-14x=180
-14x+x=90
HELP PLEASEEEEEE

-14x=180 because supplementary means 180° and you eliminate the top one because you don’t need to add back the x after taking -14 times x
