Kalo yang bias tolong dijawab ... Makasih :D

Answer 1

1.a.  10x + 15y + 12 - 8x - 7y + 17
= 10x-8x+15y-7y+12+17
=2x+8y+29
=2x+8y=-29
1.b  a+2b-4c+10a-b+5c
= a+10a+2b+5c-4c
=11a+2b+c
11a+2b=-c
1.c
8p-2q+9-6p+7q-4
=8p-6p+7q-2q+9-4
=2p+5q+5
2p+5q=-5

Answer 2

1. 
a. (10x -8x) + (15y - 7y ) + (12 + 17) = 2x + 8y + 29
b. (a + 10 a) + (2b - b) +(- 4c + 5c) = 11a + b + c
c. (8p - 6p)+ (- 2q + 7q) +( 9 - 4) = 2p + 5q + 5

d. 5x - 6y + 13 = ...
variabel = 2 (x,y)
koefisien= 2 (5,-6)
konstanta = x = 1 dan y = 1

f. 3m - 7n + 16 - 8m + 10n - 9=...
variabel = 2 (m,n)
koefisien = 4 ( 3,-7,-8,10)
konstanta= m = 2  dan n= 2
