4=19.5x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
19.5x=4
Swap sides so that all variable terms are on the left hand side.
x=\frac{4}{19.5}
Divide both sides by 19.5.
x=\frac{40}{195}
Expand \frac{4}{19.5} by multiplying both numerator and the denominator by 10.
x=\frac{8}{39}
Reduce the fraction \frac{40}{195} to lowest terms by extracting and canceling out 5.
