Answer:
x=5 or 5/2
Step-by-step explanation:
As given,
To solve (x-1)/(x-2) + (x-3)/(x-4) =10/3 we have to ttake the LCM
L.C.M. of (x-2) & (x-4) = (x-2)(x-4)
Then,
= [(x-1)(x-4)+(x-3)(x-2)]/(x-2)(x-4) = 10/3
= 3(x^2 -5x +4 + x^2 -5x +6) = 10(x-2)(x-4)
= 3( 2x^2–10x+10) = 10(x^2–6x+8)
= 6x^2–30x +30 = 10x^2–60x+80
Taking 2 as a common from both sides & cancelling it, we have,
= 3x^2–15x+15 = 5x^2–30x+40
=5x^2–3x^2–30x+15x+40–15=0
= 2x^2 -15x+25=0
Now, by the middle term splitting method,we have,
= 2x^2 -10x-5x+25=0
= 2x(x–5) -5(x-5) =0
= (2x-5)(x-5)=0
= 2x-5 = 0
So, x= 5/2
Or, x-5= 0
So, x=5
Hence, x=5 or 5/2
