Verified answer

Answer:

m= -23.8, n= 17

Explanation:

-5m-7n+3n-4m+2=2m-3mn-5

taking like terms together,

-5m-4m-7n+3n+2=2m-3mn-5

-9m-2m-4n+2+5=-3mn

-11m-4n+7=-3mn

dividing throughout by m

-11-4n/m+7/m=-3n

-11-4n/m+3n+7/m

-4n/m+3n=-11-7/m

cross multiplying...

-4n+3n = -11-7

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

m m

both m gets cancelled...

-n=-17

therefore, n= 17

substituting n=17 in either one of the equations,

-5m-7n=0

-5m-7(17) =0

-5m-119=0

-5m=119

m=119/-5

m= -23.8
