3/(x+1)=-1

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

x = - 4

Solution steps

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

Multiply both sides by

x + 1

3 = - (x + 1)

Switch sides

- (x + 1) = 3

x + 1 = - 3

Move

1

to the right side

x = - 4

Verify Solutions

Find undefined (singularity) points:

x = - 1

Combine undefined points with solutions:

x = - 4

a, u = - \frac{2 a - 3}{ka}

\frac{10}{m} = \frac{5}{11}

- 0.9 = \frac{550500 - 562750}{x}

\frac{3}{2500} = \frac{1}{x}

a, z = - \frac{3}{2 a p n}
