Question

5m - 3n = 19 ; m - on = -7

please help me​

Answer 1

Answer:

Hello mate itz Essar 03...✌️✌️❤️❤️

Step-by-step explanation:

5m - 3n =19 ...... (eq-1)

5m - 30n = - 35 .... (eq-2)

Combine Eq 1 and Eq 2

5m - 3n - 5m +30n = - 35-19

27n = 54

N = -54/27

N= - 2

Put the value of N in Eq 1

5m - 2(-2) =19

5m +4 =19

5m =19-4

5m =15

M=15/5

M=3

For check your answer is right or wrong you can check too

Check

5(3) - 2(-2) =19

15 +4 =19

19 =19

L. H. S = R. H. S

SO ANSWER Is Correct

hope it will be helpful ✌️✌️✌️✌️✌️

Answer 2

Answer:

OK!!!!!!

as the both equations have two two variables

and we have to find there values

it can be find by three methods 1) elimination method, 2)substitution method and 3) cross multipilaction method.

u can solve it by any of these methods

but the mostly preferred method is elimination method.. which is pretty simple and easy to do.

eq1) 5m-3n=19

eq2) m- n = -7

to solve both eqs multiply eq2) with ' - 5' and eq1) with ' 1 '

5m-3n=19

-5m +5n = +35

--------------------

+2n = 54

n= 17. put value of n in any Eq

take eq2) m - 17= -7

m= 10
