solvefor x,e= x/(x+2)

solve for

x, e = \frac{x}{x + 2}

x = - \frac{2 e}{e - 1}

Decimal Notation

x = - 3.16395 \dots

Solution steps

e = \frac{x}{x + 2}

Multiply both sides by

x + 2

e (x + 2) = x

Expand

e (x + 2) : e x + 2 e

e x + 2 e = x

Move

2 e

to the right side

e x = x - 2 e

Move

x

to the left side

e x - x = - 2 e

Factor

e x - x : (e - 1) x

(e - 1) x = - 2 e

Divide both sides by

e - 1

x = - \frac{2 e}{e - 1}

Verify Solutions

Find undefined (singularity) points:

x = - 2

Combine undefined points with solutions:

x = - \frac{2 e}{e - 1}

\frac{0.95}{R + 1} = 0.65

\frac{0.95}{R + 1} = 0.49

\frac{3}{8} + \frac{3}{x} = 1

\frac{1}{2} + \frac{3}{x} = 2

\frac{- 3}{k - 2} = \frac{5 k}{23}
