Question

a×b+3=27
ma puteti ajuta si pe mine va rog

Answer 1

a x b + 3 = 27

a x b = 27 - 3

a x b = 24

a x b = 1 x 24 = 2 x 12 = 3 x 8 = 4 x 6 = 6 x 4 = 8 x 3 = 12 x 2 = 24 x 1

Solutii:

( a; b ) = ( 1; 24); ( 2; 12 ); ( 3; 8 ); ( 4: 6 ); ( 6; 4 ); ( 8; 3); ( 12; 2); ( 24; 1) ∈ N

sau:

( - 1; - 24 ) ; ( - 2; - 12); ( - 3; - 8 ); ( - 4; - 6 ); ( - 6; - 4 ); ( - 8; - 3); ( - 12; - 2);

( - 24; - 1)
