2=(x+12)/(x-3)

2 = \frac{x + 12}{x - 3}

x = 18

Solution steps

2 = \frac{x + 12}{x - 3}

Multiply both sides by

x - 3

2 (x - 3) = x + 12

Expand

2 (x - 3) : 2 x - 6

2 x - 6 = x + 12

Move

6

to the right side

2 x = x + 18

Move

x

to the left side

x = 18

Verify Solutions

Find undefined (singularity) points:

x = 3

Combine undefined points with solutions:

x = 18

16 = \frac{18000}{18000 - h}

\frac{- 1.54}{z} = - 2.11

\frac{100}{x} = \frac{30}{27.5}

15 x - \frac{4}{x} = 4

\frac{9}{11 x + 1} = \frac{5}{7 x - 3}
