sederhanakanlah a. 2(× + 1) + 3(× - 1) b. -7(2× + 2) + 5(2 -3×) c. 3(× - 1) - 2(3× + 2) d. -4(3× - 1) - 5(2 -× )

a. 2x+2 + 3x-3
2x+3x -3+2
5x-1

b. -14x + -14 + 10 -15x
-14x -15x + (-14) + 10
-29x + -4

c. 3x - 3 - 6x -4
3x -6x -3 - 4
-3x -7

d. -12x + 4 - 10 - 5x
-12x -5x +4 -10
17x-6

a) 2 (×+1) + 3 (×-1) = 2x+2 + 3x -3 = 2x+3x+2-3 =5x+(-1) =5x-1
b) -7 (2x+2)+5 (2-3x) = (-14x)+(-14)+10-15x =(-14x)-15x+(-14)+10 = (-29x)+(-4) = (-29x)-4
c) 3 (×-1) - 2 (3x+2) =3x-3 - 6x+4 = 3x-6x-3+4 = (-3x)-7
d) -4 (3x-1) -5 (2-x) = (-12x)-(-4) - 10-5x =(-12x)-5x -(-4)-10 = (-17x)-(-14) = (-17x)+14
