Answer:
Step-by-step explanation:
The given pair of linear equations are,
Let, us take (1/x) equals to 'a'
Therefore, the equations, we have are,
4a + 3y = 14 ..........(iii)
3a + 4y = 23 ............(iv)
Multiplying eqn (iii) with 3 and eqn (iv) with 4,
we get,
12a + 9y = 42 ............(v)
12a + 16y = 92 ............(vi)
Now, subtract eqn (v) from (vi) ,
we get,
16y - 9y = 92 - 42
=> 7y = 50
=> y = 50/7
Therefore,
=> 4a + 150/7 = 14
=> 4a = 14- 150/7
But, a = 1/x
Hence,
