3m + 2n = 6---------------( 1 )
m + n = -24----------------( 2 )


from--------( 1 ) & --------( 2 )
multiply by ( 2 ) in -----( 2 )

3m + 2n = 6
2m + 2n = -48
-_____-____+
---------------------
m = 54 [ put in -----( 1 )]

3(54) + 2n = 6

162 + 2n = 6

2n = 6 - 162

2n = -156

n = - 78 , m = 54

▶⏩ \boxed{By \: elimination \: method:-)}

↪➡ \underline{3m + 2n = 6........................(1)}

↪➡ \underline{m + n = -24..........................(2)}

▶⏩ \boxed{Multiply \: equation \: (2) \: by \: 3.}

↪➡ \bf{3 ( m + n = -24 )}

↪➡ \underline{3m + 3n = -72........................(3)}

▶⏩ \boxed{Now, Substract \: equation \: (1) \: and \: (2).}


3m + 2n = 6.
3m + 3n = -72.
(-).....(-).........(+)
____________
-n = 78.

 \bf{=&gt; n = -78.}<br />

▶⏩ \boxed{Now, \: put \: the \: value \: of \: (n) \: in \: equation (2).}

=> m + (-78) = -24.

=> m - 78 = -24.

=> m = -24 + 78.

 \bf{=&gt; m = 54.}

✅✅ Hence, it is solved by elimination method.✔✔.
