Question

a+b=70 si a:b=4rest10

Answer 1

a+b = 70
a : b = 4 rest 10
a = 4b + 10
a /----/----/----/----/+10
b /----/
70 - 10 = 60
60 : 5 = 12 (un segment egal)
a = 4×12+10 = 48+10 = 58
b = 12

verificare:
58+12 =70

raspuns:
a = 58
b = 12

Answer 2

a+b =70
a/b =4 r 10  ;    a =4b+10

4b+10 + b =70
4b+b =70-10
5b =60
b =12
a =4b+10 =4*12 +10 =48+10 =58
v ;  58+12 =70
