Multiply by LCM

- 30 x + 70 = - 21 x

Move

70

to the right side

- 30 x = - 21 x - 70

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{70}{9}

x^{- 2} - 3 x^{- 1} = 0

(\frac{x + 1}{x})^{3} = 1^{3}

\frac{8 ^{3}}{( 2 ^{5} n - 1 ) + 1} = 33554433

x, \frac{( d ^{3} \cdot y )}{( d \cdot x ^{3} )} - 8 y = 0

\frac{14.4}{3} = \frac{6}{x}
