Question.  19

x – 4 = –2 has a solution

(A)

6

(B)

2

(C)

–6

(D)

–2

Detailed Answer with Explanation:

We want the value of x that makes the equation true.

  1. Start with the equation:
    \(x - 4 = -2\)
  2. Add 4 to both sides (to remove the \(-4\)):
    \(x - 4 + 4 = -2 + 4\)
  3. Simplify both sides:
    \(x = 2\)
  4. Check your answer by substituting \(x = 2\):
    \(2 - 4 = -2\) ✓ True

So, the solution is \(x = 2\). This matches option B.
