18-4x=0.5\times 0.4\times 5
Multiply 12 and 1.5 to get 18.
18-4x=0.2\times 5
Multiply 0.5 and 0.4 to get 0.2.
18-4x=1
Multiply 0.2 and 5 to get 1.
-4x=1-18
Subtract 18 from both sides.
-4x=-17
Subtract 18 from 1 to get -17.
x=\frac{-17}{-4}
Divide both sides by -4.
x=\frac{17}{4}
Fraction \frac{-17}{-4} can be simplified to \frac{17}{4} by removing the negative sign from both the numerator and the denominator.
