Question

Solve the following systems of equations:
2(1/x)+3 (1/y) =13
5(1/x)-4 (1/y) =-2

Answer 1

Let us write the given pair of equation as

These equation are not in the form ax+by+c=0. However, if we substitute

So, we have expressed the equations as a pair of linear equations. Now, you can use any method to solve these equations, and get p=2, q=3
