Allow me. Kindly mark me brainliest and thank !!!
Step-by-step explanation:
3z - 4 + 2 ( z = 5 )
= 3 (5) - 4 + 2
= (3 x 5) - 4 + 2 →→→ (Additional step. Don't do it if you understand that brackets mean multiply)
= 15 - 4 + 2
Applying BODMAS rule (Brackets Of Division, Multiplication, Addition, Subtraction)
= 15 - 4 + 2
= 15 - 6
