Question

What is the solution for log z + 12 = 9?A: 000.1 B: -1,000 C: -0.001 D: 1,000

Answer 1

Answer:

z + 12 = 9

Reorder the terms:

12 + z = 9

Solving

12 + z = 9

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.

Add '-12' to each side of the equation.

12 + -12 + z = 9 + -12

Combine like terms: 12 + -12 = 0

0 + z = 9 + -12

z = 9 + -12

Combine like terms: 9 + -12 = -3

z = -3

Simplifying

z = -3
