13-(28)/x =4+8/x

13 - \frac{28}{x} = 4 + \frac{8}{x}

x = 4

Solution steps

13 - \frac{28}{x} = 4 + \frac{8}{x}

Move

13

to the right side

- \frac{28}{x} = \frac{8}{x} - 9

Multiply both sides by

x

- 28 = 8 - 9 x

Switch sides

8 - 9 x = - 28

Move

8

to the right side

- 9 x = - 36

Divide both sides by

- 9

x = 4

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 4

\frac{x}{x - 6} = \frac{x - 2}{x + 6}

\frac{36}{x} = \frac{42}{28}

\frac{45}{x + 3} = \frac{20}{10 - x}

100 = \frac{1600}{( 1 + r ) ^{2}}

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