Знайдiть корiнь рiвняння 5/12 + (x-3/20)=1 4/15
5/12 + ( х - 3/20 ) = 1 4/15 х - 3/20 = 1 4/15 - 5/12 х - 3/20 = 19/15 - 5/12 х - 3/20 = 76/60 - 25/60 х - 3/20 = 51/60 х - 3/20 = 17/20 х = 17/20 + 3/20 х = 20/20 х = 1
5/12+(х-3/20)=1 4/15 5/12+х-3/20= 1 4/15 х=1 4/15+3/20-5/12 х=19/15+3/20-5/12 х=76/60+9/60-25/60 х=60/60 х=1
5/12+(х-3/20)=14/15
