\left(x-5\right)\left(2b-5\right)=\left(x-3\right)\left(5x-4\right)+2\left(x-5\right)\left(x-3\right)\times \frac{1}{2}
Multiply both sides of the equation by 2\left(x-5\right)\left(x-3\right), the least common multiple of 2x-6,2x-10,2.
2xb-5x-10b+25=\left(x-3\right)\left(5x-4\right)+2\left(x-5\right)\left(x-3\right)\times \frac{1}{2}
Use the distributive property to multiply x-5 by 2b-5.
2xb-5x-10b+25=5x^{2}-19x+12+2\left(x-5\right)\left(x-3\right)\times \frac{1}{2}
Use the distributive property to multiply x-3 by 5x-4 and combine like terms.
2xb-5x-10b+25=5x^{2}-19x+12+\left(x-5\right)\left(x-3\right)
Multiply 2 and \frac{1}{2} to get 1.
2xb-5x-10b+25=5x^{2}-19x+12+x^{2}-8x+15
Use the distributive property to multiply x-5 by x-3 and combine like terms.
2xb-5x-10b+25=6x^{2}-19x+12-8x+15
Combine 5x^{2} and x^{2} to get 6x^{2}.
2xb-5x-10b+25=6x^{2}-27x+12+15
Combine -19x and -8x to get -27x.
2xb-5x-10b+25=6x^{2}-27x+27
Add 12 and 15 to get 27.
2xb-10b+25=6x^{2}-27x+27+5x
Add 5x to both sides.
2xb-10b+25=6x^{2}-22x+27
Combine -27x and 5x to get -22x.
2xb-10b=6x^{2}-22x+27-25
Subtract 25 from both sides.
2xb-10b=6x^{2}-22x+2
Subtract 25 from 27 to get 2.
\left(2x-10\right)b=6x^{2}-22x+2
Combine all terms containing b.
\frac{\left(2x-10\right)b}{2x-10}=\frac{6x^{2}-22x+2}{2x-10}
Divide both sides by 2x-10.
b=\frac{6x^{2}-22x+2}{2x-10}
Dividing by 2x-10 undoes the multiplication by 2x-10.
b=\frac{3x^{2}-11x+1}{x-5}
Divide 6x^{2}-22x+2 by 2x-10.
