The equation can be simplified as follows:
1 - 2(1 + x)
To simplify further, distribute the -2:
1 - 2 - 2x
Combine like terms:
-1 - 2x
So the simplified expression is -1 - 2x.
The correct answer is B. -1 - 2x.
To simplify the expression 1-2(x+1), follow these steps:
Step 1: Distribute the -2 to the terms inside the parentheses.
1-2x - 2(1)
Step 2: Simplify the expression inside the parentheses.
1-2x - 2
Step 3: Combine like terms.
1-2x-2 = -2x-1
So, the simplified expression is -2x-1.
Therefore, the answer is option B. -2x-1.
