Za 1 dobre rozwiązanie daje naj z góry thx za rozwiązania

ZAQQQ

a) -x-4y+12+0,5x-3y

-(-1)-4*(-2)+12+0,5*(-1)-3*(-2) = 1+8+12-0,5+6 = 26,5

b) 6-(-3a)+7b-2a

6-(-3*(-2))+7*(-5)-2*(-2) = 6-6-35+4 = -31

c) 13x-7y+(-8z)-20x-(7z)+6y

13*(-2)-7*(-3)-8*(-4)-20*(-2)-7*(-4)+6*(-3) = -26+21+32+40+28-18 = 77
