Question:
Solve the following systems of equations:
$\frac{2}{x}+\frac{3}{y}=13$
$\frac{5}{x}-\frac{4}{y}=-2$
Solution:
The given equations are:
$\frac{2}{x}+\frac{3}{y}=13$..(i)
$\frac{5}{x}-\frac{4}{y}=-2 \ldots(i i)$
Multiply equation (i) by 4 and equation (ii) by 3 and add both equations we get
Put the value of $x$ in equation $(i)$, we get
$\frac{2}{\frac{1}{2}}+\frac{3}{y}=13$
$\Rightarrow \frac{3}{y}=9$
$\Rightarrow y=\frac{1}{3}$
Hence the value of $x=\frac{1}{2}$ and $y=\frac{1}{3}$.
