(x^3)/(x+x+x)=12

\frac{x ^{3}}{x + x + x} = 12

x = 6, x = - 6

Solution steps

\frac{x ^{3}}{x + x + x} = 12

Simplify

\frac{x ^{3}}{x + x + x} : \frac{x ^{2}}{3}

\frac{x ^{2}}{3} = 12

Multiply both sides by

3

x^{2} = 36

Solve

x^{2} = 36 : x = 6, x = - 6

x = 6, x = - 6

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 6, x = - 6

x + \frac{4}{x} = - 5

y, x = \frac{1}{y + 2}

\frac{x + 3}{x - 4} = \frac{x - 5}{x + 4}

\frac{x}{4} - \frac{5}{2 x} = - \frac{1}{4 x}

1 - \frac{2}{x ^{2} + 1} = 0
