Answer 1

Answer:

Step-by-step explanation:

Equations reducible to pair of linear equations in 2 variables

Sometimes we come across pair of equation which are not linear but can be reduced to linear form by making some suitable substitutions.

E.g.  2/x + 3/y = 13     & 5/x + 4/y = 2

This equation is not a linear equation, but if we substitute 1/x with a & 1/y with b, then the equation becomes

2a+ 3b =13   & 5a + 4b = 2. This is now a pair of linear equation in 2 variables.

After finding the values of variables a & b, we can easily find x as 1/a & y as 1/b.
