-3z + 7 = -7 - 10z

7z = -14
Divide by 7
Z = -2

Answer:
- 16
Step-by-step explanation:
following the rules as set out in PEMDAS
4² - 2(3 × 5 + 1) ← evaluate exponent term
= 16 - 2(3 × 5 + 1) ← evaluate multiplication inside parenthesis
= 16 - 2(15 + 1)
= 16 - 2(16) ← perform the multiplication
= 16 - 32 ← evaluate subtraction
= - 16
