x \cdot 9 = 72

Divide both sides by

9

x = 8

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 8

z, x = \frac{y}{z}

\frac{x}{( x - 6 ) ( x + 5 )} = 0

10 = \frac{2 a ( 5 ) + 3 ( 6 )}{2 a}

\frac{2}{x} - 1 = \frac{2 - x}{x + 3}

441 y^{- 4} - 58 y^{- 2} + 1 = 0
