0.39=1.3x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
1.3x=0.39
Swap sides so that all variable terms are on the left hand side.
x=\frac{0.39}{1.3}
Divide both sides by 1.3.
x=\frac{39}{130}
Expand \frac{0.39}{1.3} by multiplying both numerator and the denominator by 100.
x=\frac{3}{10}
Reduce the fraction \frac{39}{130} to lowest terms by extracting and canceling out 13.
