\frac{1}{x+6\times 16+12\times 18}\times 24\times 18=0.385
Multiply both sides of the equation by 2.
\frac{1}{x+96+216}\times 24\times 18=0.385
Do the multiplications.
\frac{1}{x+312}\times 24\times 18=0.385
Add 96 and 216 to get 312.
\frac{1}{x+312}\times 432=0.385
Multiply 24 and 18 to get 432.
\frac{432}{x+312}=0.385
Express \frac{1}{x+312}\times 432 as a single fraction.
432=0.385\left(x+312\right)
Variable x cannot be equal to -312 since division by zero is not defined. Multiply both sides of the equation by x+312.
\frac{432}{0.385}=x+312
Divide both sides by 0.385.
\frac{432000}{385}=x+312
Expand \frac{432}{0.385} by multiplying both numerator and the denominator by 1000.
\frac{86400}{77}=x+312

x=\frac{86400}{77}-312
Subtract 312 from both sides.
x=\frac{62376}{77}
Subtract 312 from \frac{86400}{77} to get \frac{62376}{77}.
