u-6=-5+(30)/u

u - 6 = - 5 + \frac{30}{u}

u = 6, u = - 5

Solution steps

u - 6 = - 5 + \frac{30}{u}

Move

6

to the right side

u = \frac{30}{u} + 1

Multiply both sides by

u

u^{2} = 30 + u

Solve

u^{2} = 30 + u : u = 6, u = - 5

u = 6, u = - 5

Verify Solutions

Find undefined (singularity) points:

u = 0

Combine undefined points with solutions:

u = 6, u = - 5

\frac{7 ^{n}}{2 ^{n}} = (3.5)^{n}

\frac{3}{2} = \frac{24}{x}

y, x = 2 - \frac{12}{y + 5}

\frac{7}{6} = \frac{8}{x + 4}

\frac{x}{2} = \frac{6}{x} + 2
