\frac{3.2}{0.5}=4.76-x
Divide both sides by 0.5.
\frac{32}{5}=4.76-x
Expand \frac{3.2}{0.5} by multiplying both numerator and the denominator by 10.
4.76-x=\frac{32}{5}
Swap sides so that all variable terms are on the left hand side.
-x=\frac{32}{5}-4.76
Subtract 4.76 from both sides.
-x=\frac{32}{5}-\frac{119}{25}
Convert decimal number 4.76 to fraction \frac{476}{100}. Reduce the fraction \frac{476}{100} to lowest terms by extracting and canceling out 4.
-x=\frac{160}{25}-\frac{119}{25}
Least common multiple of 5 and 25 is 25. Convert \frac{32}{5} and \frac{119}{25} to fractions with denominator 25.
-x=\frac{160-119}{25}
Since \frac{160}{25} and \frac{119}{25} have the same denominator, subtract them by subtracting their numerators.
-x=\frac{41}{25}
Subtract 119 from 160 to get 41.
x=-\frac{41}{25}
Multiply both sides by -1.
