Which of the following is a simplified version of 12 -2(x+1) =5?

A. -2x+ 10= 5

B. -2x + 13=5

C. 10x+1=5

D. 10x + 10 = 5

1 answer

To simplify the equation \(12 - 2(x+1) = 5\), let's work through the steps:

  1. Distribute \(-2\) into the parentheses:
    \[ 12 - 2(x + 1) = 12 - 2x - 2 \]
  2. Combine the constants \(12\) and \(-2\):
    \[ 10 - 2x = 5 \]
  3. Rearranging gives us:
    \[ -2x + 10 = 5 \]

So, the simplified version of the equation \(12 - 2(x+1) = 5\) is \( -2x + 10 = 5\).

The correct option is A. -2x + 10 = 5.
