Answer:
x= 5 or 5/2
Step-by-step explanation:
solve the equation
((x-1)(x-4)+(x-3)(x-2))/((x-2)(x-4))=10/3
((x²-5x+4+x²-5x+6)/((x-2)(x-4))=10/3
6x²-30x+30=10x²-60x+80
4x²-30x+50=0
2x²-15x+25=0
(x-5)(2x-5)=0
x= 5 or 5/2

Answer:
(x-1)/(x-2)+(x-3)/ (x-4)=3 1/3
=> (x-1)(x-4)+(x-2)(x-3)=10/3.(x-2)(x-4)
=> 3{x^2-x-4x+4+x^2-2x-3x+6}=
10(x^2-2x-4x+8)
=> 3(2x^2-10x+10)=10(x^2-6x+8)
=> 6x^2-30x+30=10x^2-60x+80
=> 10x^2-60x+80-6x^2+30x-30=0
=> 4x^2-30x+50=0
=> 2x^2-15x+25=0
=> 2x^2-10x-5x+25=0
=> 2x(x-5)-5(x-5)=0
=> (x-5)(2x-5)=0
=> x-5=0
=> x=5
again, 2x-5=0
=> 2x=5
=> x=5/2=2 1/2
so , x=5 , 2 1/2
