If y = xx−3 x x − 3 + xx+4 x x + 4 find y w..

Question 1 Report

If y = $\frac{x}{x - 3}$ + $\frac{x}{x + 4}$ find y when x = -2

\frac{3}{5}

\frac{3}{5}

\frac{7}{5}

\frac{3}{5}

Answer Details

y = $\frac{x}{x - 3}$ + $\frac{x}{x + 4}$ when x = -2
y = $\frac{- 2}{- 5}$ + $\frac{(- 2)}{- 2 + 4}$
= $\frac{- 2}{5}$ + $\frac{- 2}{2}$
= $\frac{4 + - 10}{10}$
= $\frac{- 14}{10}$
= - $\frac{7}{5}$
