3\times 1.8x=729-405
Multiply both sides of the equation by 5.
5.4x=729-405
Multiply 3 and 1.8 to get 5.4.
5.4x=324
Subtract 405 from 729 to get 324.
x=\frac{324}{5.4}
Divide both sides by 5.4.
x=\frac{3240}{54}
Expand \frac{324}{5.4} by multiplying both numerator and the denominator by 10.
x=60
Divide 3240 by 54 to get 60.
