To solve the equation \(3x - 7 - 2x + 5 = 6\), we can follow these steps:

Step 1: Combine like terms on the left side of the equation.
In this case, combine \(3x\) and \(-2x\), and also \(-7\) and \(+5\).
This gives us:
\( (3x - 2x) + (-7 + 5) = 6 \)
which simplifies to:
\( x - 2 = 6 \)

Step 2: Add 2 to both sides of the equation to isolate the variable \(x\).
This gives us:
\( x - 2 + 2 = 6 + 2 \)
Simplifying this results in:
\( x = 8 \)

Step 3: Confirm the solution by substituting \(x = 8\) back into the original equation.
This checks that the left side equals the right side:
\( 3(8) - 7 - 2(8) + 5 \)
Calculating gives: \( 24 - 7 - 16 + 5 = 6 \)
which is true.

Final answers:

  • Step 1: Combine like terms.
  • Step 2: Isolate \(x\).
  • Step 3: Verify the solution.

For Question 2, the answer is:

  • \( \mathbf{x = 8} \)
