Question from Pulane, a student: Hi math centre I've been trying to solve these equations for days now please help Please help me solve them simultaneously |
Hi Pulane,
I would first write the equations as
\begin{eqnarray*}
6 \frac{1}{x} - \frac{1}{y} & = & 4\\
9 \frac{1}{x} + 1 & = & -2 \frac{1}{y}.
\end{eqnarray*}
Now let $s = \frac{1}{x}, t = \frac{1}{y}$ and solve for $s$ and $t.$
Make sure you verify your answer.
