Olá boa tarde meu nome é "Guilherme" sou de Brasil e vou resolver a sua pergunta

a ) 2x - 2y = 12

{ a 2

{ b 2

{ c 12

/\ = b elevado 2 -4 a.c

/\ = (2) elevado 2 -4 . 24

/\ = 4 -4 . 24

/\ = 24

X = -b+/ /\ = 2 - 5

S = {20,10}

b) 29. - 3y = -2

{ a = 29

{ b = -3

{ c = -2

/\ = b elevado 2 -4 a.c

/\ = (-6) -4 . 58

/\ = -10 . 58

/\ = -48

X = b + / /\ = -3 + 24
