Question

2u+15v=17uv
5u+5v=36uv solve the equation by elimination methode​

Answer 1

Answer:

Given ⤵

2u+15v=17uv ... (1)

5u+5v=36uv ... (2)

To find ⤵

➡Solve by elimination method.

Solution ⤵

➡multiplying eq. (2) by 3

15u+15v= 108uv .... (3)

Subtracting eq. (1) from (3)

15u+15v=108uv

2u+15v=17uv

- - -

___________

13u= 91uv

u = 91uv/13

u = 7uv

Putting the value u=7vu in eq. (1)

14uv+15v=17uv

15v=17uv-14uv

15v= 3uv

v = 3uv/15

v= uv/5

Hence u= 7uv and v= uv/5
