A-b=794 --> a= 794+b
A÷b=4 ; rest=83 --> a=4×b+83
794+b= 4×b +83 /-83 -b
711= 3×b /÷3
237=b
A=794+b= 794+237= 1031
A÷b=4 ; rest=83 --> a=4×b+83
794+b= 4×b +83 /-83 -b
711= 3×b /÷3
237=b
A=794+b= 794+237= 1031
a-b=794
a:b= 4 rest 83
a=4b+83
Inlocuim:
4b+83-b=794
3b+83=794
3b=794-83
3b=711
b=237
a= 7x237+83
a=1659+83

a:b= 4 rest 83
a=4b+83
Inlocuim:
