1/(1+x)=1

Solution

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

x = 0

Solution steps

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

Multiply both sides by

1 + x

1 = 1 + x

Subtract

1

from both sides

1 - 1 = 1 + x - 1

Simplify

0 = x

Switch sides

x = 0

Verify Solutions

Find undefined (singularity) points:

x = - 1

Combine undefined points with solutions:

x = 0

\frac{4}{x} = \frac{29}{8 x + 3}

\frac{3}{4 x ^{2}} = 12

0.4 = \frac{0.2}{\frac{x - 2}{2}}

- \frac{5}{4 x} + \frac{5}{32 x} = 35

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