x = −6(34
x − 2) + 4

Sorry, I cannot solve these equations without more information. Please provide any missing information or context.

Let's break down each equation step-by-step:

1. 8 - 12:
To solve this equation, simply subtract 12 from 8:
8 - 12 = -4

Answer: -4

2. x = -6(34(x - 2)) + 4:
To solve this equation, we need to apply the order of operations (parentheses, exponents, multiplication and division, addition and subtraction) to simplify the expression.

Step 1: Simplify inside the parentheses:
x - 2

Step 2: Multiply -6 by the expression inside the parentheses:
-6 * (34(x - 2))

Step 3: Simplify exponent 34:
-6 * (34x - 68)

Step 4: Distribute -6 to each term inside the parentheses:
-6 * 34x + 6 * (-68)
-204x - 408

Step 5: Add 4 to the resulting expression:
-204x - 408 + 4
-204x - 404

Answer: x = -204x - 404
