Answer:
The value of x in terms of b is (-3/b)
The value of x when b is 3 is -1
===============================
Explanation:
The given function is :
-2 (bx - 5) = 16
Divide both sides by 2
bx - 5 = 16/(-2) = -8
Add 5 to both sides
bx = -8 + 5 = -3
Divide both sides by (b)
∴ x = -3/b
∴ The value of x in terms of b is (-3/b)
When b = 3 ⇒ ∴ x = -3/b = -3/3 = -1
