Question

subtract the sum of 3a – 7b + 2c and 4a + 2b + 3c from the sum of 5a – 6b
and a – 4b +c​

Answer 1

Answer:

-a-5b-4c

Step-by-step explanation:

(5a-6b)+(a-4b+c)

5a-6b+a-4b+c

6a-10b+c

(3a–7b+2c)+ (4a+2b+3c)

3a-7b+2c+4a+2b+3c

7a-5b+5c

(6a-10b+c)-(7a-5b+5c)

6a-10b+c- 7a+5b-5c

-a-5b-4c
