5/(d+3)=(-7)/(d+5)

\frac{5}{d + 3} = \frac{- 7}{d + 5}

d = - \frac{23}{6}

Decimal Notation

d = - 3.83333 \dots

Solution steps

\frac{5}{d + 3} = \frac{- 7}{d + 5}

Cross multiply

5 d + 25 = - 7 d - 21

Move

25

to the right side

5 d = - 7 d - 46

Move

7 d

to the left side

12 d = - 46

Divide both sides by

12

d = - \frac{23}{6}

Verify Solutions

Find undefined (singularity) points:

d = - 3, d = - 5

Combine undefined points with solutions:

d = - \frac{23}{6}

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

\frac{1}{2 x} + \frac{1}{3 x} = 5

\frac{6 x}{x + 1} = 4 - \frac{6}{x + 1}

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

t, R = \frac{d}{1 - t}
