genteeeeeeeee me ajudaaaa pfvvrrrrr
coloca os calculos pfvrr

Explicação passo-a-passo:
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, ;-;
