Question

(a-3)×(b+4)=12 a=? b=?​

Answer 1

Răspuns:

daca a=0 => (0-3)×(b+4)=12 => -3×(b+4)=12=> b+4=-4 =>b=-8

daca b=0 => (a-3)×4=12=> a=6

daca a=-1 => -4×(b+4)=12=>b=-7

daca b=-1 => a-3=7

Asa faci la toate numerele(ma gandesc ca toate numerele fac parte din numerele Z)

a=-9,-3,-1,0,1,2,3,4,5,6,7,9,15
