6.15=(6.4)/((1+x))

6.15 = \frac{6.4}{( 1 + x )}

x = \frac{5}{123}

Decimal Notation

x = 0.04065 \dots

Solution steps

6.15 = \frac{6.4}{( 1 + x )}

Simplify

\frac{6.4}{( 1 + x )} : \frac{6.4}{1 + x}

6.15 = \frac{6.4}{1 + x}

Multiply both sides by

1 + x

6.15 (1 + x) = 6.4

Multiply both sides by

100

615 (1 + x) = 640

Divide both sides by

615

1 + x = \frac{128}{123}

Move

1

to the right side

x = \frac{5}{123}

Verify Solutions

Find undefined (singularity) points:

x = - 1

Combine undefined points with solutions:

x = \frac{5}{123}

\frac{1}{x - 1} + 3 = \frac{10}{x - 1}

2 - \frac{72}{x ^{2}} = 0

\frac{x ^{2} + x - 12}{x ^{2}} = 0

\frac{15}{6} = \frac{25}{n}

4 = \frac{- 16}{n}
