39.2=1.4x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
1.4x=39.2
Swap sides so that all variable terms are on the left hand side.
x=\frac{39.2}{1.4}
Divide both sides by 1.4.
x=\frac{392}{14}
Expand \frac{39.2}{1.4} by multiplying both numerator and the denominator by 10.
x=28
Divide 392 by 14 to get 28.
