4/(x-3)= 2/(5-x)

\frac{4}{x - 3} = \frac{2}{5 - x}

x = \frac{13}{3}

Decimal Notation

x = 4.33333 \dots

Solution steps

\frac{4}{x - 3} = \frac{2}{5 - x}

Cross multiply

20 - 4 x = 2 x - 6

Move

20

to the right side

- 4 x = 2 x - 26

Move

2 x

to the left side

- 6 x = - 26

Divide both sides by

- 6

x = \frac{13}{3}

Verify Solutions

Find undefined (singularity) points:

x = 3, x = 5

Combine undefined points with solutions:

x = \frac{13}{3}

\frac{( n + 1 ) !}{( n - 2 ) !} = n^{3} - n

5 x^{- 2} - 9 x^{- 1} - 2 = 0

a, b + \frac{m}{a} = z

\frac{18}{7 + c} = \frac{10}{7 - c}

\frac{6}{2 x + 7} = \frac{10}{3 x - 8}
