0.5\left(x-0.5x+0.5\right)=\frac{2}{3}\left(x-1\right)
Use the distributive property to multiply -0.5 by x-1.
0.5\left(0.5x+0.5\right)=\frac{2}{3}\left(x-1\right)
Combine x and -0.5x to get 0.5x.
0.25x+0.25=\frac{2}{3}\left(x-1\right)
Use the distributive property to multiply 0.5 by 0.5x+0.5.
0.25x+0.25=\frac{2}{3}x+\frac{2}{3}\left(-1\right)
Use the distributive property to multiply \frac{2}{3} by x-1.
0.25x+0.25=\frac{2}{3}x-\frac{2}{3}
Multiply \frac{2}{3} and -1 to get -\frac{2}{3}.
0.25x+0.25-\frac{2}{3}x=-\frac{2}{3}
Subtract \frac{2}{3}x from both sides.
-\frac{5}{12}x+0.25=-\frac{2}{3}
Combine 0.25x and -\frac{2}{3}x to get -\frac{5}{12}x.
-\frac{5}{12}x=-\frac{2}{3}-0.25
Subtract 0.25 from both sides.
-\frac{5}{12}x=-\frac{2}{3}-\frac{1}{4}
Convert decimal number 0.25 to fraction \frac{25}{100}. Reduce the fraction \frac{25}{100} to lowest terms by extracting and canceling out 25.
-\frac{5}{12}x=-\frac{8}{12}-\frac{3}{12}
Least common multiple of 3 and 4 is 12. Convert -\frac{2}{3} and \frac{1}{4} to fractions with denominator 12.
-\frac{5}{12}x=\frac{-8-3}{12}
Since -\frac{8}{12} and \frac{3}{12} have the same denominator, subtract them by subtracting their numerators.
-\frac{5}{12}x=-\frac{11}{12}
Subtract 3 from -8 to get -11.
x=-\frac{11}{12}\left(-\frac{12}{5}\right)
Multiply both sides by -\frac{12}{5}, the reciprocal of -\frac{5}{12}.
x=\frac{-11\left(-12\right)}{12\times 5}
Multiply -\frac{11}{12} times -\frac{12}{5} by multiplying numerator times numerator and denominator times denominator.
x=\frac{132}{60}
Do the multiplications in the fraction \frac{-11\left(-12\right)}{12\times 5}.
x=\frac{11}{5}
Reduce the fraction \frac{132}{60} to lowest terms by extracting and canceling out 12.
