2.) a.) (3x + 5) - (2 - 2x) = 3x + 2x + 5 - 2 = 5x + 3
b.) (5x + 4) - (-4x+7) = 5x + 4x + 4 - 7 = 9x - 3
3.) a.) 5(2p + 3q) - 6(p - 3q) + 3(p + q + 1) = (10p + 15q) - (6p - 18q) + (3p + 3q + 3) = 10p - 6p + 3p + 15q + 18q + 3q + 3 = 7p + 36q + 3
a. 9 (x + 2) dari 5 (x - 3) = (9x + 18) - ( 5x - 15)
= (9x - 5x) - (18 - (-15)
= 4x - 33
2.
a. (3x + 5) - (2 - 2x) = (3x - (-2x)) - (5 - 2)
= 5x - 3
b. (5x + 4) - ((-4x) + 7) = (15x (-4x)) - (4-7)
= 19x - 3
3.
a. 5 (2p + 3q) -6 (p - 3q) + 3 (p + q + 1)
10p + 15q -6p +18q +3p + 3q + 3
10p -6p +3p +15q +18q +3q +3
= 7p + 36q + 3
