0-\frac{x-3}{0.5}=-1.6
Anything times zero gives zero.
-\frac{x-3}{0.5}=-1.6
Anything plus zero gives itself.
-\left(\frac{x}{0.5}+\frac{-3}{0.5}\right)=-1.6
Divide each term of x-3 by 0.5 to get \frac{x}{0.5}+\frac{-3}{0.5}.
-\left(\frac{x}{0.5}+\frac{-30}{5}\right)=-1.6
Expand \frac{-3}{0.5} by multiplying both numerator and the denominator by 10.
-\left(\frac{x}{0.5}-6\right)=-1.6
Divide -30 by 5 to get -6.
-\frac{x}{0.5}-\left(-6\right)=-1.6
To find the opposite of \frac{x}{0.5}-6, find the opposite of each term.
-\frac{x}{0.5}+6=-1.6
The opposite of -6 is 6.
-\frac{x}{0.5}=-1.6-6
Subtract 6 from both sides.
-\frac{x}{0.5}=-7.6
Subtract 6 from -1.6 to get -7.6.
\frac{x}{0.5}=\frac{-7.6}{-1}
Divide both sides by -1.
\frac{x}{0.5}=\frac{-76}{-10}
Expand \frac{-7.6}{-1} by multiplying both numerator and the denominator by 10.
\frac{x}{0.5}=\frac{38}{5}
Reduce the fraction \frac{-76}{-10} to lowest terms by extracting and canceling out -2.
x=\frac{38}{5}\times 0.5
Multiply both sides by 0.5.
x=\frac{38}{5}\times \frac{1}{2}
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{38\times 1}{5\times 2}
Multiply \frac{38}{5} times \frac{1}{2} by multiplying numerator times numerator and denominator times denominator.
x=\frac{38}{10}
Do the multiplications in the fraction \frac{38\times 1}{5\times 2}.
x=\frac{19}{5}
Reduce the fraction \frac{38}{10} to lowest terms by extracting and canceling out 2.
