Question

(4a - 7b + 5c) - (2a + 3b - c) Me ajudeeeeeemmm

Answer 1

Yo Gang,

4a − 7b + 5c − (2a + 3b − c)

Distribuir o sinal negativo:

4a − 7b + 5c + −1 (2a + 3b − c)

4a + −7b + 5c + −1 (2a) + - 1 (3b) + - 1 (−c)

4a + −7b + 5c + −2a + −3b + c

Combinar Termos Semelhantes:



(4a + −2a) + (- 7b + −3b) + (5c + c)

2a + −10b + 6c

+ com - = -

= 2a - 10b + 6c

Dnd Gang!
