Step by step explanation

Answer 2

HIIIIII

Answer:

= a + 5b + 4c

Step-by-step explanation:

Solution 1

Sum of 3a – 7b + 2c and 4a + 2b + 3c

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

= 7a - 5b + 5c

Solution 2

Sum of 5a – 6b and a – 4b + c

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

= 6a - 10b + c

Difference = Solution 2 - Solution 1

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

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

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

Difference = a + 5b + 4c
