2a-3b+4c from the sum of a+3b-4c,4a-b+9c and -2b+3c+a
​

Answer 1

Answer:

= 4a + 3b + 4c

Step-by-step explanation:

The sum the sum of a + 3b - 4c, 4a - b + 9c and - 2b + 3c + a,

a + 3b - 4c + 4a - b + 9c + ( -2b ) + 3c + a

= a + 4a + a + 3b - 2b - b - 4c + 9c + 3c

= 6a + 3b - 3b - 4c + 12c

= 6a + 0 + 8c

= 6a + 8c

Subtract  2a - 3b + 4c from the sum of a + 3b - 4c, 4a - b + 9c and

- 2b + 3c + a,

6a + 8c - ( 2a - 3b + 4c )

= 6a + 8c - 2a + 3b - 4c

= 6a - 2a + 3b + 8c - 4c

= 4a + 3b + 4c
