x\times 1.8=4\times 7.2
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 4x, the least common multiple of 4,x.
x\times 1.8=28.8
Multiply 4 and 7.2 to get 28.8.
x=\frac{28.8}{1.8}
Divide both sides by 1.8.
x=\frac{288}{18}
Expand \frac{28.8}{1.8} by multiplying both numerator and the denominator by 10.
x=16
Divide 288 by 18 to get 16.
