5*(x-y+12z)= -7-(2a-b+c)= -(12-124y-175)= (12x-6y-12z);(-6) (24y-15y-30z);3= Jak bY Co To ten,,*,, Symbol to mnożenie

5*(x-y+12z)= 5x-5y+2,5z -7-(2a-b+c)= -7-2a+b-c -(12-124y-175)= -12+124y+175= 163+124y (12x-6y-12z);(-6)= -2x+y+2z (24y-15y-30z);3= 8y-5y-10z= 3y-10z

5*(x-y+12z)=5x-5y+2½z -7-(2a-b+c)=-7-2a+b-c -(12-124y-175)=-12+124y+175=163+124y (12x-6y-12z);(-6)=-2x+y+2z (24y-15y-30z);3=8y-5y-10z=3y-10z Chyba dobrze jest..
