5=((6.9*21)/(1+6.9x))

5 = (\frac{6.9 \cdot 21}{1 + 6.9 x})

x = 4.05507 \dots

Solution steps

5 = (\frac{6.9 \cdot 21}{1 + 6.9 x})

Simplify

\frac{6.9 \cdot 21}{1 + 6.9 x} : \frac{144.9}{1 + 6.9 x}

5 = \frac{144.9}{1 + 6.9 x}

Multiply both sides by

1 + 6.9 x

5 (1 + 6.9 x) = 144.9

Divide both sides by

5

1 + 6.9 x = 28.98

Move

1

to the right side

6.9 x = 27.98

Divide both sides by

6.9

x = 4.05507 \dots

Verify Solutions

Find undefined (singularity) points:

x = - \frac{10}{69}

Combine undefined points with solutions:

x = 4.05507 \dots

1 = - \frac{1}{1 + C}

6 = - \frac{9}{v}

\frac{4}{x} + \frac{3}{x + 1} = 3

\frac{2}{3} = \frac{7}{x} - 4

x, y = \frac{x - 3}{x + 2}
