Question

simplify 6a+2b-4c+6a+2b-4c-(6a+2b-4c)​

Answer 1

Answer:

6a + 2b - 4c

Step-by-step explanation:

6a+2b-4c+6a+2b-4c-(6a+2b-4c)

= 6a+2b-4c+6a+2b-4c-6a-2b+4c

= 6a + 6a - 6a + 2b +2b - 2b - 4c - 4c + 4c

= 6a + 2b - 4c

Answer 2

Step-by-step explanation:

$6a + 2b - 4c + 6a + 2b - 4c - (6a + 2b - 4c)$

$6a + 2b - 4c + 6a + 2b - 4c - 6a - 2b + 4c$

$6a + 6a - 6a + 2b + 2b - 2b - 4c - 4c + 4c$

$cancel \: 2 \: positives \: + 6a \: and \: + 6a$

$+ 2b \: and \: + 2b$

$- 4c \: and \: - 4c$

$now \: left \:$

$- 6a - 2b + 4c$
