A. =(7-2)a +5b = 5a + 5b b. =(5-3)x + (7-2)y = 2x+5y c. =(7×2) - (a×2)+(3-6)y = 14 - 2a - 3y atau -2a - 3y +14 d. 15 + 3(x-2) = 15 + 3x - 6 = 9 + 3x atau 3x+9 e. = 12p+8 - 6p = (12-6)p +8 = 6p+8 f. = 10p - 3 + 2p = (10+2)p - 3 = 12p - 3 g. = 5x - 10y - 6x +3y = (5-6)x - 10y +3y = -x -7y semoga dapat membantu
= 5a + 5b
b. =(5-3)x + (7-2)y
= 2x+5y
c. =(7×2) - (a×2)+(3-6)y
= 14 - 2a - 3y atau -2a - 3y +14
d. 15 + 3(x-2)
= 15 + 3x - 6
= 9 + 3x atau 3x+9
e. = 12p+8 - 6p
= (12-6)p +8
= 6p+8
f. = 10p - 3 + 2p
= (10+2)p - 3
= 12p - 3
g. = 5x - 10y - 6x +3y
= (5-6)x - 10y +3y
= -x -7y
semoga dapat membantu
