(64)/(8+u)=30

\frac{64}{8 + u} = 30

u = - \frac{88}{15}

Decimal Notation

u = - 5.86666 \dots

Solution steps

\frac{64}{8 + u} = 30

Multiply both sides by

8 + u

64 = 30 (8 + u)

Switch sides

30 (8 + u) = 64

Divide both sides by

30

8 + u = \frac{32}{15}

Move

8

to the right side

u = - \frac{88}{15}

Verify Solutions

Find undefined (singularity) points:

u = - 8

Combine undefined points with solutions:

u = - \frac{88}{15}

- 12 x^{- 13} + 13 x^{- 14} = 0

\frac{45}{x} = 235

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

\frac{140 + 0.25 x}{x} = 1

1 - \frac{8}{x - 5} = \frac{3}{x}
