\frac{4}{\frac{4x}{x}+\frac{2}{x}}=0.24
To add or subtract expressions, expand them to make their denominators the same. Multiply 4 times \frac{x}{x}.
\frac{4}{\frac{4x+2}{x}}=0.24
Since \frac{4x}{x} and \frac{2}{x} have the same denominator, add them by adding their numerators.
\frac{4x}{4x+2}=0.24
Variable x cannot be equal to 0 since division by zero is not defined. Divide 4 by \frac{4x+2}{x} by multiplying 4 by the reciprocal of \frac{4x+2}{x}.
\frac{4x}{2\left(2x+1\right)}=0.24
Factor the expressions that are not already factored in \frac{4x}{4x+2}.
\frac{2x}{2x+1}=0.24
Cancel out 2 in both numerator and denominator.
2x=0.24\left(2x+1\right)
Variable x cannot be equal to -\frac{1}{2} since division by zero is not defined. Multiply both sides of the equation by 2x+1.
2x=0.48x+0.24
Use the distributive property to multiply 0.24 by 2x+1.
2x-0.48x=0.24
Subtract 0.48x from both sides.
1.52x=0.24
Combine 2x and -0.48x to get 1.52x.
x=\frac{0.24}{1.52}
Divide both sides by 1.52.
x=\frac{24}{152}
Expand \frac{0.24}{1.52} by multiplying both numerator and the denominator by 100.
x=\frac{3}{19}
Reduce the fraction \frac{24}{152} to lowest terms by extracting and canceling out 8.
