Rozwiąż równanie
7m - 4n = -14
2m + 3n = 25
'm' i 'n' mają mieć takie same wartości w obu równaniach.
7m-4n=-14 I*3
2m+3n=25 I*4
21m-12n= -42
8m+12n=100
+ ---------------------
29m=58 I /29
m=2
2m+3n=25
2*2+3n=25
4+3n=25
3n=25-4
3n=21 I/3
n=7
W= (7*3)-(-4*2)=29
Wn=(-14*3)-(-4*25)=58
Wm=(7*25)-(-14*2)=203
Wn/W=2
Wm/W=7
