(20)/m =5

Solution

\frac{20}{m} = 5

m = 4

Solution steps

\frac{20}{m} = 5

Multiply both sides by

m

20 = 5 m

Switch sides

5 m = 20

Divide both sides by

5

m = 4

Verify Solutions

Find undefined (singularity) points:

m = 0

Combine undefined points with solutions:

m = 4

\frac{x - 3}{x + 7} = \frac{2}{5}

\frac{3}{x - 2} = - \frac{1}{x} - 2

\frac{1}{x - 1} - \frac{3}{x - 4} = 0

\frac{- 7}{x + 4} = \frac{3}{x - 5}

x, y = \frac{1}{x + 1}
