1 answer

Let's solve each equation step by step:

Question 1:
\( 12 + 3x = 36 \)
Subtract 12 from both sides:
\( 3x = 24 \)
Divide by 3:
\( x = 8 \)

Question 2:
\( x^2 + 5 = 8 \)
Subtract 5 from both sides:
\( x^2 = 3 \)
Take the square root:
\( x = \sqrt{3} \) (approximately 1.732)
The closest integer option is not provided.

Question 3:
\( -2x + 3 = 25 \)
Subtract 3 from both sides:
\( -2x = 22 \)
Divide by -2:
\( x = -11 \)

Question 4:
\( 10x - 6 = 5x + 19 \)
Subtract \( 5x \) from both sides:
\( 5x - 6 = 19 \)
Add 6 to both sides:
\( 5x = 25 \)
Divide by 5:
\( x = 5 \)

Question 5:
\( 8x - 4 = 6x + 2 \)
Subtract \( 6x \) from both sides:
\( 2x - 4 = 2 \)
Add 4 to both sides:
\( 2x = 6 \)
Divide by 2:
\( x = 3 \)

Summary of Answers:

  1. \( x = 8 \)
  2. \( x = \sqrt{3} \) (approximately needs context on integer selection)
  3. \( x = -11 \)
  4. \( x = 5 \)
  5. \( x = 3 \)

Please check the integer responses for Question 2, as \( \sqrt{3} \) does not match any of the provided options.
