Zad. 4 #zerujemy takie same składniki i patrzymy co zostanie
a) -17x - 10x - 13x - 11x + 11x + 13x + 10x + 17x = - 10x - 13x - 11x + 11x + 13x + 10x = - 13x - 11x + 11x + 13x = - 11x + 11x = 0
b) -10x - 8x - 6x - 2x + 2x + 4x + 6x + 8x = -10x - 8x - 6x - 2x + 4x + 6x + 10x = - 8x - 6x - 2x + 4x + 6x = - 8x - 2x = -10x
Zad. 5
a) 2 * 4x = 8x
b) 3x * 5 = 15x
c) 2/5x * 5 = 2x
d) 3/7x * 1/3 = 1/7x
e) 2x * (-5) = -10x
f) (-2) * 0,2x = -0,4x
g) (-1/3x) * (-2) = 2/3x
h) 24x : 3 = 8x
i) 6x : (-3) = -2x
Proszę :)
