4/(s+5)=8

\frac{4}{s + 5} = 8

s = - \frac{9}{2}

Decimal Notation

s = - 4.5

Solution steps

\frac{4}{s + 5} = 8

Multiply both sides by

s + 5

4 = 8 (s + 5)

Switch sides

8 (s + 5) = 4

Divide both sides by

8

s + 5 = \frac{1}{2}

Move

5

to the right side

s = - \frac{9}{2}

Verify Solutions

Find undefined (singularity) points:

s = - 5

Combine undefined points with solutions:

s = - \frac{9}{2}

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

3 = \frac{1}{4} - \frac{5}{y}

\frac{[ x + 5 ] ^{2} - 4}{x + 3} = 0

2 = \frac{x + 8}{x - 2}

(\frac{1400}{y} - 3) (y - 3) = 1175
