#color(green)(d=-30#

#3/5d+5=1/3d-3#

#:.3/5d+25/5=1/3d-9/3#

#:.3/5d-1/3d=-9/3-25/5#

multiply L.H.S andR.H.S.by 15

#:.15(3/5d)-15(1/3d)=15(-9/3)-15(25/5)#

#:.9d-5d=-45-75#

#:.4d=-120#

#:.color(green)(d=-30#

substitute #color(green)(d=-30#

#:.3/5(-30)+5=1/3(-30)-3#

#:.-18+5=-10-3#

#:.color(green)(-13=-13#
