5=2.8x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
2.8x=5
Swap sides so that all variable terms are on the left hand side.
x=\frac{5}{2.8}
Divide both sides by 2.8.
x=\frac{50}{28}
Expand \frac{5}{2.8} by multiplying both numerator and the denominator by 10.
x=\frac{25}{14}
Reduce the fraction \frac{50}{28} to lowest terms by extracting and canceling out 2.
