8\left(x-1\right)-5\left(x-2\right)=10\left(x-1\right)-4\left(x-2\right)\times \frac{1}{20}
Multiply both sides of the equation by 40, the least common multiple of 5,8,4,10,20.
8x-8-5\left(x-2\right)=10\left(x-1\right)-4\left(x-2\right)\times \frac{1}{20}
Use the distributive property to multiply 8 by x-1.
8x-8-5x+10=10\left(x-1\right)-4\left(x-2\right)\times \frac{1}{20}
Use the distributive property to multiply -5 by x-2.
3x-8+10=10\left(x-1\right)-4\left(x-2\right)\times \frac{1}{20}
Combine 8x and -5x to get 3x.
3x+2=10\left(x-1\right)-4\left(x-2\right)\times \frac{1}{20}
Add -8 and 10 to get 2.
3x+2=10x-10-4\left(x-2\right)\times \frac{1}{20}
Use the distributive property to multiply 10 by x-1.
3x+2=10x-10-\frac{4}{20}\left(x-2\right)
Multiply 4 and \frac{1}{20} to get \frac{4}{20}.
3x+2=10x-10-\frac{1}{5}\left(x-2\right)
Reduce the fraction \frac{4}{20} to lowest terms by extracting and canceling out 4.
3x+2=10x-10-\frac{1}{5}x-\frac{1}{5}\left(-2\right)
Use the distributive property to multiply -\frac{1}{5} by x-2.
3x+2=10x-10-\frac{1}{5}x+\frac{-\left(-2\right)}{5}
Express -\frac{1}{5}\left(-2\right) as a single fraction.
3x+2=10x-10-\frac{1}{5}x+\frac{2}{5}
Multiply -1 and -2 to get 2.
3x+2=\frac{49}{5}x-10+\frac{2}{5}
Combine 10x and -\frac{1}{5}x to get \frac{49}{5}x.
3x+2=\frac{49}{5}x-\frac{50}{5}+\frac{2}{5}
Convert -10 to fraction -\frac{50}{5}.
3x+2=\frac{49}{5}x+\frac{-50+2}{5}
Since -\frac{50}{5} and \frac{2}{5} have the same denominator, add them by adding their numerators.
3x+2=\frac{49}{5}x-\frac{48}{5}
Add -50 and 2 to get -48.
3x+2-\frac{49}{5}x=-\frac{48}{5}
Subtract \frac{49}{5}x from both sides.
-\frac{34}{5}x+2=-\frac{48}{5}
Combine 3x and -\frac{49}{5}x to get -\frac{34}{5}x.
-\frac{34}{5}x=-\frac{48}{5}-2
Subtract 2 from both sides.
-\frac{34}{5}x=-\frac{48}{5}-\frac{10}{5}
Convert 2 to fraction \frac{10}{5}.
-\frac{34}{5}x=\frac{-48-10}{5}
Since -\frac{48}{5} and \frac{10}{5} have the same denominator, subtract them by subtracting their numerators.
-\frac{34}{5}x=-\frac{58}{5}
Subtract 10 from -48 to get -58.
x=-\frac{58}{5}\left(-\frac{5}{34}\right)
Multiply both sides by -\frac{5}{34}, the reciprocal of -\frac{34}{5}.
x=\frac{-58\left(-5\right)}{5\times 34}
Multiply -\frac{58}{5} times -\frac{5}{34} by multiplying numerator times numerator and denominator times denominator.
x=\frac{290}{170}
Do the multiplications in the fraction \frac{-58\left(-5\right)}{5\times 34}.
x=\frac{29}{17}
Reduce the fraction \frac{290}{170} to lowest terms by extracting and canceling out 10.
