Question

poderiam me ajudar??​

Answer 1

Resposta:

a) x = 3, y = 2

b) x = 1, y = 2

c) x = 3, y = 2

d) x = 4, y = 1

e) x = 3, y = 4

Explicação passo a passo:

a)

$3 + 2 = 5\\3 - 2 = 1$

b)

$(4.1)-2 = 2\\(3.1)+2(2) \\3+4 = 7$

c)

$4(3)+2(2) = \\12 + 4 = 16\\5(3)-3(2) =\\15-6 = 9$

d)

$4-3(1) =\\4-3 = 1\\2(4)+5(1)\\8+5 = 13$

e)

$2(3)+4 =\\6+4 = 10\\3+3(4)\\3 + 12\\=15$
