Question 42

Question. 42

The equations x + 1 = 0 and 2x + 2 = 0 have the same solution.

Answer:

true

Detailed Answer with Explanation:

First equation: \(x + 1 = 0\)

  1. Subtract \(1\) from both sides: \(x + 1 - 1 = 0 - 1\)
  2. Simplify: \(x = -1\)

Second equation: \(2x + 2 = 0\)

  1. Subtract \(2\) from both sides: \(2x + 2 - 2 = 0 - 2\)
  2. Simplify: \(2x = -2\)
  3. Divide both sides by \(2\): \(\dfrac{2x}{2} = \dfrac{-2}{2}\)
  4. Simplify: \(x = -1\)

Conclusion: Both equations give the same solution, \(x = -1\). So the statement is true.
