(12)/x =2

Solution

\frac{12}{x} = 2

x = 6

Solution steps

\frac{12}{x} = 2

Multiply both sides by

x

12 = 2 x

Switch sides

2 x = 12

Divide both sides by

2

x = 6

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 6

x, z = \frac{y}{2 x + 3 y}

400 x - \frac{10800}{x ^{2}} = 0

\frac{2}{x} + \frac{4}{x} = 3

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

\frac{9}{x} = \frac{6}{8}
