3 x = \frac{20}{7 - x}

x = \frac{21 - 201}{6}, x = \frac{21 + 201}{6}

Decimal Notation

x = 1.13709 \dots, x = 5.86290 \dots

Solution steps

3 x = \frac{20}{7 - x}

Multiply both sides by

7 - x

3 x (7 - x) = 20

Solve

3 x (7 - x) = 20 : x = \frac{21 - 201}{6}, x = \frac{21 + 201}{6}

x = \frac{21 - 201}{6}, x = \frac{21 + 201}{6}

Verify Solutions

Find undefined (singularity) points:

x = 7

Combine undefined points with solutions:

x = \frac{21 - 201}{6}, x = \frac{21 + 201}{6}

u + \frac{2}{3} u - 1 + 1 = 6 - \frac{u}{u} + 1.2

\frac{7 y + 4}{y + 2} = \frac{- 4}{3}

\frac{( 9 x + 7 )}{2 - ( x - \frac{( x - 2 )}{2} )} = 36

\frac{x ^{2} + 1}{( x ^{2} ) - 5 ( a + \frac{1}{x} ) + 2} = 0

\frac{\frac{22}{15}}{( \frac{1}{3} - 5 x )} = - \frac{22}{5}
