3+1/(x+1)=(4x)/(x+1)

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

x = 4

Solution steps

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

Multiply both sides by

x + 1

3 (x + 1) + 1 = 4 x

Expand

3 (x + 1) + 1 : 3 x + 4

3 x + 4 = 4 x

Move

4

to the right side

3 x = 4 x - 4

Move

4 x

to the left side

- x = - 4

Divide both sides by

- 1

x = 4

Verify Solutions

Find undefined (singularity) points:

x = - 1

Combine undefined points with solutions:

x = 4

3 (x + 1)^{- 2} = 1

v, c = \frac{q}{v}

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

\frac{1}{x} = \frac{5}{30}

2 = \frac{8}{- A}
