b.9m - 6n - 7 dari -m + 8
c.-6p + 3q dari -3p - 7q
d.-11a + 3b - c dari-3a - 5b + 2c

Answer 1

A. 2y+6z
c. 3p-10q
d. 8a-8b+3c

Answer 2

A. 3y-2z dari 5y+4z
= 5y+4z -(3y-2z)
= 5y+4z-3y+2z
= 5y-3y+4z+2z
= 2y+6z

B. 9m-6n-7 dari -m+8
= -m+8 -(9m-6n-7)
= -m+8 -9m+6n+7
= -m-9m+6n+8+7
= -10m+6n+15

C. -6p+3q dari -3p-7q
= -3p-7q -(-6p+3q)
= -3p-7q +6p-3q
= -3p+6p-7q-3q
= 3p-10q

D. -11a+3b-c dari -3a-5b+2c
= -3a-5b+2c -(-11a+3b-c)
= -3a-5b+2c +11a-3b+c
= -3a+11a-5b-3b+2c+c
= 8a-8b+3c
