Niech głupi się do tego nie pcha. Całe obliczenia!!! -(5z+½)-1/12= 2×(3t-5+12)= (12t-2-6t):(-2)=

-(5z+½)-1/12=-5z-½-¹/₁₂=-5z-⁶/₁₂-¹/₁₂=-5z-⁷/₁₂ 2×(3t-5+12)=2*(3t+7)=6t+14 (12t-2-6t):(-2)= (6t-2):(-2)=-3t+1

-(5z + ½) -1/12 = -5z - ½ -1/12 = -5z -½⁶₆ n-1/12 = -5z - 6/12 - 1/12= -5z -7/12 2x(3t-5+12)= 6xt + (2x*(-5)) + (2x * 12) = 6xt -10x +24x (12t-2-6t): (-2) = (12t : (-2)) - (2: (-2)) - (6t : (-2)) = -6t -(-1) - (-3t)= -6t +1 + 3t = -3t +1
