Answer 1

Odpowiedź:

x+z

-1+3=2

---------------------------------------------------------------------------------------------------

3z-2y+x

3 · 3 - 2 · 4 + (-1) = 9 - 8 - 1 = 0

-------------------------------------------------------------------------------------------

2z-y

2 · 3 - 4 = 6-4=2

---------------------------------------------------------------------------------

2y + 6x

2 · 4 + 6· (-1) =  8 - 6 = 2

---------------------------------------------------------------------------------

xyz + 10

-1 · 3 · 4  + 10 = - 12 + 10 = -2

---------------------------------------------------------------------------------

5x + 2y + z

5 · (-1) + 2 · 4 + 3 = -5 + 8 + 3 = 6

---------------------------------------------------------------------------------

yz + 10x

4 · 3 + 10 · (-1) = 12 -10 = 2

---------------------------------------------------------------------------------

y-z+x

4-3+(-1) = 0

---------------------------------------------------------------------------------

2xz+y

2 · (-1) · 3 + 4 = -2 ·3+4 = -4+4 = 0

---------------------------------------------------------------------------------

(z-x) :2

(3-(-1)) :2 = 4:2=2

---------------------------------------------------------------------------------

12 - 5z - x

12 - 5  · 3 - (-1) = 12 - 15 + 1 = -2
