Răspuns :
a,b-nr. cautate
a+b=29
a:b=6 rest 1=>a=b×6+1
______
a,b=?
______
b×6+1+b=29
b×7=28
b=4
a=4×6+1
a=25
a+b=29
a:b=6 rest 1=>a=b×6+1
______
a,b=?
______
b×6+1+b=29
b×7=28
b=4
a=4×6+1
a=25
a+b=29
a:b=6 rest 1 => a=6b+1
Prima metodă :
a |—|—|—|—|—|—|+1|
b |—|
29-1=28
28:7=4 ( b )
4×6+1=25 ( a )
A doua metodă:
6b+1+b=29
7b+1=29
7b=29-1
7b=28
b=28:7 => b=4
a=4×6+1 => a=25
a:b=6 rest 1 => a=6b+1
Prima metodă :
a |—|—|—|—|—|—|+1|
b |—|
29-1=28
28:7=4 ( b )
4×6+1=25 ( a )
A doua metodă:
6b+1+b=29
7b+1=29
7b=29-1
7b=28
b=28:7 => b=4
a=4×6+1 => a=25
