7/(d+5)=(10)/(d+2)

\frac{7}{d + 5} = \frac{10}{d + 2}

d = - 12

Solution steps

\frac{7}{d + 5} = \frac{10}{d + 2}

Cross multiply

7 d + 14 = 10 d + 50

Move

14

to the right side

7 d = 10 d + 36

Move

10 d

to the left side

- 3 d = 36

Divide both sides by

- 3

d = - 12

Verify Solutions

Find undefined (singularity) points:

d = - 5, d = - 2

Combine undefined points with solutions:

d = - 12

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

4.5 \cdot 1 0^{- 7} = \frac{50}{x}

\frac{1 + 1}{2 ( 4 x - 6 )} = - 2

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

\frac{3}{5} = \frac{30}{x}
