x = -1, y = 4, z = 3
3x + z = 3×(-1) + 3 = -3+3 = 0
x+z = -1+3 = 2
3z - 2y + x = 3×3 -2×4 -1 = 9-8-1 = 0
3×(-1)+3= -3+3 = 0
2z-y = 2×3 - 4 = 6-4 = 2
2y + 6x = 2×4 + 6×(-1) = 8-6 = 2
xyz + 10 = (-1)×4×3 = -12+10 = -2
5x + 2y = 5×(-1) + 2×4 = -5+8 = 3
yz + 10x = 4×3 + 10×(-1) = 12-10 = 2
Y-Z + x = 4-3-1 = 0
(-1) + 5 = 4
2x2 = 2×(-1) × 2 = -2×2 = -4
(2-x): 2 = (2+1)÷2 = 3÷2 = 1,5
12 - 5z - x = 12-5×3+1 = 12-15+1 = -2
12-59 = -47
