Question

Find the value of 4m-3n+p-q for
m=n=o,p=8​

Answer 1

Answer:

hope it help you

Step-by-step explanation:

4m+3n=18;3m−2

Let 4m+3n=18 -

and 3m−2n=5 -

Multiplying the first eduation by 2 , we get 8m+6n=36 -- (3)

Multiplying the second equation by 3 , we get 9m−6n=15 -- (4)

Adding equations 3, and 4 , we get

17m=51

=>m=3

Now, putting m=3 in equation 1 we get, 12+3n=18

=>3n=6

=>n=2
