4/x =-1

Solution

\frac{4}{x} = - 1

x = - 4

Solution steps

\frac{4}{x} = - 1

Multiply both sides by

x

4 = - x

Move

x

to the left side

4 + x = 0

Move

4

to the right side

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = - 4

a, \frac{c - b}{a} = 1

x^{- 1} + y^{- 1} = \frac{x + y}{x y}

\frac{2}{3 x} = 4

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

\frac{2}{n} + 3 (2 - 4)^{2} = 16
