2x-4\left(x-5\right)=8x-1
Multiply both sides of the equation by 8, the least common multiple of 4,2,8.
2x-4x+20=8x-1
Use the distributive property to multiply -4 by x-5.
-2x+20=8x-1
Combine 2x and -4x to get -2x.
-2x+20-8x=-1
Subtract 8x from both sides.
-10x+20=-1
Combine -2x and -8x to get -10x.
-10x=-1-20
Subtract 20 from both sides.
-10x=-21
Subtract 20 from -1 to get -21.
x=\frac{-21}{-10}
Divide both sides by -10.
x=\frac{21}{10}
Fraction \frac{-21}{-10} can be simplified to \frac{21}{10} by removing the negative sign from both the numerator and the denominator.
