z+4/(z+1)=3

z + \frac{4}{z + 1} = 3

z = 1

Solution steps

z + \frac{4}{z + 1} = 3

Multiply both sides by

z + 1

z (z + 1) + 4 = 3 (z + 1)

Solve

z (z + 1) + 4 = 3 (z + 1) : z = 1

z = 1

Verify Solutions

Find undefined (singularity) points:

z = - 1

Combine undefined points with solutions:

z = 1

\frac{2}{x} = 4

\frac{7}{p} = \frac{8}{9}

\frac{6 x}{( x ^{2} + 3 ) ^{2}} = 0

82000 = (\frac{42000 p}{100 - p})

z + \frac{36}{z + 3} = 9
