The equation `3x+ 7 = 10 ` has 1 as its solution.

Answer

To verify if 1 is indeed the solution of the equation \(3x + 7 = 10\), we will substitute \(x\) with 1 and check if both sides of the equation are equal.

### Step-by-Step Solution:

1. **Write down the original equation:**
\[ 3x + 7 = 10 \]

2. **Substitute \(x\) with 1:**
\[ 3(1) + 7 = 10 \]

3. **Calculate the left-hand side:**
\[ 3 \times 1 = 3 \]
\[ 3 + 7 = 10 \]

4. **Now, compare both sides of the equation:**
\[ 10 = 10 \]

Since both sides of the equation are equal, we can conclude that the solution \(x = 1\) is correct.

### Final Answer:
Yes, the equation \(3x + 7 = 10\) has 1 as its solution.
