Step-by-step explanation:
Let 1/x be a. So, the equations will become,
4a+3y = 14 -----(1)
3a-4y = 23 -----(2)
Multiplying (1) by 4 and (2) by 3 and adding them,
16a+12y + 9a-12y = 56 + 69
=> 25a = 125
=> a = 5
=> x = 1/5
From (1),
4 * 5 + 3y = 14
=> 20 + 3y = 14
=> 3y = -6
=> y = 2
So, the answer is x = 1/5 and y = 2.
