Question

4/x+3y=14. 3/x-4y=23 from elemination method ​

Answer 1

4/x + 3y=14 and 3/x - 4y=23

Let 1/x = m,

 

4m + 3y = 14...(1) and 3m - 4y = 23 ... (2)

Multiply (1) by 4 and (2) by 3, we get

 

16m + 12y = 56   ... (3) and 9m - 12y = 69 .... (3)

 

Adding (3) and (4), we get

 

25m = 125

→ m = 5

From (1),

4(5) + 3y = 14

→ 3y = 14 - 20

→ y = -2 and m = 1/x = 5 → x = 1/5
