0-\frac{1}{2}x=\frac{3}{5}x-0.5
Multiply 0 and 78 to get 0.
-\frac{1}{2}x=\frac{3}{5}x-0.5
Anything plus zero gives itself.
-\frac{1}{2}x-\frac{3}{5}x=-0.5
Subtract \frac{3}{5}x from both sides.
-\frac{11}{10}x=-0.5
Combine -\frac{1}{2}x and -\frac{3}{5}x to get -\frac{11}{10}x.
x=-0.5\left(-\frac{10}{11}\right)
Multiply both sides by -\frac{10}{11}, the reciprocal of -\frac{11}{10}.
x=-\frac{1}{2}\left(-\frac{10}{11}\right)
Convert decimal number -0.5 to fraction -\frac{5}{10}. Reduce the fraction -\frac{5}{10} to lowest terms by extracting and canceling out 5.
x=\frac{-\left(-10\right)}{2\times 11}
Multiply -\frac{1}{2} times -\frac{10}{11} by multiplying numerator times numerator and denominator times denominator.
x=\frac{10}{22}
Do the multiplications in the fraction \frac{-\left(-10\right)}{2\times 11}.
x=\frac{5}{11}
Reduce the fraction \frac{10}{22} to lowest terms by extracting and canceling out 2.
