Odpowiedź:
a) 2(3p - 4) + [tex]\frac{4-2p}{2}[/tex] = 6p - 8 + 2 - 1p = 5p - 6
b) 3(2 - 5m) - [tex]\frac{12m+9}{3}[/tex] = 6 - 15m - (4m + 3) = 6 - 15m - 4m - 3 = -19m + 3
c) -5(4t - 2) - [tex]\frac{30t - 5}{5}[/tex] = -20t + 10 - (6t - 1) = -20t + 10 - 6t + 1 = -26t + 11
d) [tex]\frac{6x-14}{2}[/tex] + [tex]\frac{6 + 15x}{3}[/tex] = 3x - 7 + 2 + 5x = 8x - 5
e) [tex]\frac{12-20y}{-4} + \frac{14-7y}{7}[/tex] = -3 + 5y + 2 - 1y = 4y -1
