Question

5m-8n=9and n=-1/2 find m=?

Answer 1

ANSWER :-

5m - 8n = 9 ( Given :- n = 1/2 )

Put the value of n is the equation.

5m - 8n = 9

5m - 8 ( 1/2 ) = 9

5m - 8/2 = 9

Taking L.C.M

10m -- 8 = 9

2

10m -- 8 = 9 × 2

10m = 18 + 8

10m = 26

m = 2.6

Answer 2

Here is the answer to your question!!

Your question;

5m - 8n = 9 n = - 1/2

We have been given the value of n,

So we just have to put the value in the equation and can find the value of m.

So; 5m - 8n = 9

= 5m - 8 (-1/2 ) = 9

=> 5m -8/2 = 9

=> (10m -8)/2 = 9

=> 10m -8 = 9 × 2 = 18

=> 10m = 18 +8 = 26

=> m = 26/10 =2.6

=> m = 2.6

Hope it helped!
