1 answer

To solve the equation \( 2|2x + 3| = 10 \), we can first divide both sides by 2:

\[ |2x + 3| = 5 \]

Next, we'll set up two cases based on the definition of absolute value:

Case 1: \[ 2x + 3 = 5 \] Subtracting 3 from both sides: \[ 2x = 2 \] Dividing by 2: \[ x = 1 \]

Case 2: \[ 2x + 3 = -5 \] Subtracting 3 from both sides: \[ 2x = -8 \] Dividing by 2: \[ x = -4 \]

Now we have two solutions: \( x = 1 \) and \( x = -4 \).

Putting the smaller value in the first box, we have: \[ x = -4 \] or \[ x = 1 \]

So the final answers are:

  • First box: \(-4\)
  • Second box: \(1\)
