(1)/(c) +5=(2)/(3)\ \|\ subtract\ 5\ to\ both\ sides \\\\(1)/(c) =(2)/(3)-5\\\\(1)/(c) =(2)/(3)-(15)/(3)\\\\(1)/(c) = (-13)/(3)\\\\-13c=3\ \ | \ divide \ both \ sides\ by\ (-13)\\\\c=-(3)/(13)




(1)/(c+5) = (2)/(3) \\\\2(c+5) =3\\\\2c+10=3\ \ |\ subtract\ 10\ to\ both\ sides \\\\ 2c=3-10 \\\\2c=-7 \ \ | \ divide \ both \ sides\ by\ 2 \\\\c=-(7)/(2)\\\\c=-3.5
