Question

primul 2 va rog este urgent dau coroana

Answer 1

a:b=5 rest 2

(a+b):(a-b)=1 rest 12

_____________________________

=>

5b+2=a

1(a-b)+12=a+b

a-b+12=a+b

(a+b)-(a-b)=2b MEREU

(a+b)-(a-b)=12

2b=12

b=6

a=6×5+2

a=32

Sau

5b+2=a

a-b+12=a+b

5b+2-b+12=5b+2+b

4b+14=6b+2

4b+14-2=6b

4b+12=6b

2b=12

b=6

a=32

Sper ca te-am ajutat!
