{(x-4)/(x-5)}+{(x-6)/(x-7)}=10/3
Answers
Answer:
Step-by-step explanation: first of all do LCM, (x-4)(x-7)+(x-6)(x-5)/(x-5)(x-7)=10/3 x²-7x-4x+28+x²-5x-6x+30/x²-7x-5x+35=10/3 2x²-22x+58/x²-12x+35=10/3 now cros multiplication,
6x²-66x+174=10x²-120x+350
10x²-6x²-120x+66x=174-350
4x²-54x+176=0
now take common,
4x(x-54/4+44)=0
x-54/4+44=0
x-(54+176)/4=0
x-220/4=0
x-55=0
x=55
