Ineed answers for this 4 questions !

1 → - 13 , 2 → 31, 3 → 22, 4 → 19

substitute the given values for x, y and z into the expressions

1. xy - z = (2 × - 5) - 3 = - 10 - 3 = - 13

2. 6(z - x) + y² = 6(3 - 2) + (- 5)² = (6 × 1) + 25 = 6 + 25 = 31

3. 2x - 3y + z = (2 × 2) - (3 × - 5) + 3 = 4 - (- 15) + 3 = 4 + 15 + 3 = 22

4. = = = = 19
