108=(38.8)/(1+12x)*4

108 = \frac{38.8}{1 + 12 x} \cdot 4

x = 0.03641 \dots

Solution steps

108 = \frac{38.8}{1 + 12 x} \cdot 4

Simplify

\frac{38.8}{1 + 12 x} \cdot 4 : \frac{155.2}{1 + 12 x}

108 = \frac{155.2}{1 + 12 x}

Multiply both sides by

1 + 12 x

108 (1 + 12 x) = 155.2

Divide both sides by

108

1 + 12 x = 1.43703 \dots

Move

1

to the right side

12 x = 0.43703 \dots

Divide both sides by

12

x = 0.03641 \dots

Verify Solutions

Find undefined (singularity) points:

x = - \frac{1}{12}

Combine undefined points with solutions:

x = 0.03641 \dots

\frac{- 1}{x - 1} = 1 - \frac{2}{x + 5}

x + \frac{1}{x} = - 6

x + \frac{1}{x} = - 3

\frac{12}{x + 3} + \frac{x}{x - 3} = 4

\frac{11}{8} = \frac{3}{j}
