Question

Simplify:
(3a+b+c)+(2a+3b-c)-(a+b+c)​

Answer 1

Answer:

4a + 3b - c

Step-by-step explanation:

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

= ( 3a + 2a - a) + ( b + 3b - b) + ( c - c - c)

= 4a + 3b - c

Answer 2

Answer:

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

=>6a+5b-1c

=>a+b= -6-5+1

=>a+b= -11+1

=>a+b= -10
