(2x+2)/(x^2+2x-15)= 1/3

\frac{2 x + 2}{x ^{2} + 2 x - 15} = \frac{1}{3}

x = 7, x = - 3

Solution steps

\frac{2 x + 2}{x ^{2} + 2 x - 15} = \frac{1}{3}

Cross multiply

(2 x + 2) \cdot 3 = x^{2} + 2 x - 15

Solve

(2 x + 2) \cdot 3 = x^{2} + 2 x - 15 : x = 7, x = - 3

x = 7, x = - 3

Verify Solutions

Find undefined (singularity) points:

x = 3, x = - 5

Combine undefined points with solutions:

x = 7, x = - 3

\frac{3}{( 5 - x )} + \frac{2}{( 4 - x )} = \frac{8}{( x + 2 )}

\frac{4}{∣ x + 1 ∣ - 2} = ∣ x + 1 ∣

\frac{- 5}{11} = \frac{5 b - 4}{2 b + 12}

\frac{x ^{2} + 3}{4 x} = \frac{1}{4}

6 \frac{m}{( m + 222 )} \cdot 100 = 10, m
