To solve the equation \( 3 - |6 - 3x| + 7 = 4 \), first simplify the equation:
\[
3 + 7 - |6 - 3x| = 4
\]
This simplifies to:
\[
10 - |6 - 3x| = 4
\]
Now, isolate the absolute value term:
\[
10 - 4 = |6 - 3x|
\]
This leads to:
\[
|6 - 3x| = 6
\]
Next, we solve the absolute value equation \( |6 - 3x| = 6 \). This breaks down into two cases:
1. \( 6 - 3x = 6 \)
2. \( 6 - 3x = -6 \)
**Case 1:**
\[
6 - 3x = 6
\]
Subtracting 6 from both sides gives:
\[
-3x = 0 \implies x = 0
\]
**Case 2:**
\[
6 - 3x = -6
\]
Subtracting 6 from both sides gives:
\[
-3x = -12 \implies x = 4
\]
Thus, the solutions are \( x = 0 \) and \( x = 4 \).
Therefore, there are **2 solutions** to the equation \( 3 - |6 - 3x| + 7 = 4 \).
\[
3 + 7 - |6 - 3x| = 4
\]
This simplifies to:
\[
10 - |6 - 3x| = 4
\]
Now, isolate the absolute value term:
\[
10 - 4 = |6 - 3x|
\]
This leads to:
\[
|6 - 3x| = 6
\]
Next, we solve the absolute value equation \( |6 - 3x| = 6 \). This breaks down into two cases:
1. \( 6 - 3x = 6 \)
2. \( 6 - 3x = -6 \)
**Case 1:**
\[
6 - 3x = 6
\]
Subtracting 6 from both sides gives:
\[
-3x = 0 \implies x = 0
\]
**Case 2:**
\[
6 - 3x = -6
\]
Subtracting 6 from both sides gives:
\[
-3x = -12 \implies x = 4
\]
Thus, the solutions are \( x = 0 \) and \( x = 4 \).
Therefore, there are **2 solutions** to the equation \( 3 - |6 - 3x| + 7 = 4 \).
