e=(a-re)/(e-r)

e = \frac{a - re}{e - r}

r \neq = e; 0 = a - e^{2}

Solution steps

e = \frac{a - re}{e - r}

Multiply both sides by

e - r

e (e - r) = a - er

Solve

e (e - r) = a - er :

True for all

r; 0 = a - e^{2}

r \neq = e

Verify Solutions

Find undefined (singularity) points:

r = e

Since the equation is undefined for:

e

r \neq = e; 0 = a - e^{2}

2 z^{2} - \frac{15}{z ^{2}} + 7 = 0

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

y, \frac{y + 2}{5 y - 1} = x

\frac{x - 1}{x - 3} = \frac{9}{5}

6 = x^{- 2}
