x\times 0,4=5\times 0,6
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 5x, the least common multiple of 5;x.
x\times 0,4=3
Multiply 5 and 0,6 to get 3.
x=\frac{3}{0,4}
Divide both sides by 0,4.
x=\frac{30}{4}
Expand \frac{3}{0,4} by multiplying both numerator and the denominator by 10.
x=\frac{15}{2}
Reduce the fraction \frac{30}{4} to lowest terms by extracting and canceling out 2.
