Answer 1

Answer:

- 8a - 7b +8 - 3c

Step-by-step explanation:

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

= ( 2 + 1 - 1 )a + ( 3 - 2 + 2 )b + ( 1 + 2 )c

= ( 3 - 1 ) a + ( 1 + 2 )b + 3c

= 2a + 3b + 3c

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

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

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

= 8a + -7b -8 -3c
