1) m+n=110
n=m+30
m+m+30=110
2m=110-30=>m=80:2=>m=40
n=40+30=>n=70
____________
2) e+v=102
e=v+12
v+12+v=102
2v=102-12
v=90:2=>v=45 timbre are Viorel
e=45+12=57 timbre are Ema
Răspuns:
1) m + n = 110
n = m + 30
m = ?
n = ?
30
n |---|-|
} 110
m |---|
110 - 30 = 80 ( m2 )
80 ÷ 2 = 40 ( m )
110 - 40 = 70 ( n )
2) E + V = 102 Timbre
E = V + 12
E = ?
V = ?
12
E |---|-|
} 102
V |---|
102 - 12 = 90
90 : 2 = 45
102 - 45 = 47
