\frac{2}{x} = \frac{5}{10}

x = 4

Solution steps

x \cdot 5 = 20

Divide both sides by

5

x = 4

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 4

x, \frac{2 ( y + 3 )}{x} = 2 w

\frac{15}{20} = \frac{3}{k}

R^{3} = 5 + \frac{H}{a}

37.5 = \frac{150 x}{200 - x}

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