Answer 2

Resposta:

c) x = -6

d) x = -1

Explicação passo-a-passo:

c) 3 (x+2) = 2 (x+3) - 6

aplicando a distributiva:

3x + 6 = 2x + 6 - 6

colocando números de um lado e letras de outro:

3x - 2x = + 6 - 6 - 6

somando:

1x = -6

d) 3 (x+1) + 2 = 5 + 2 (x-1)

aplicando a distributiva:

3x + 3 + 2 = 5 + 2x - 1

colocando números de um lado e letras de outro:

3x - 2x = 5 - 1 - 3 - 2

somando:

1x = -1

e) 5 (2x + 7 - 1 = 4 (x-5) + 9

tu esqueceu o parênteses, ;-;
