To determine the nature of the solution for the equation \( 3x + 7(x + 1) = 2(6x + 5) - 2x \), let's simplify both sides.
Start by expanding and simplifying:
### Left Side:
\[
3x + 7(x + 1) = 3x + 7x + 7 = 10x + 7
\]
### Right Side:
\[
2(6x + 5) - 2x = 12x + 10 - 2x = 10x + 10
\]
Now the equation looks like this:
\[
10x + 7 = 10x + 10
\]
Next, we will isolate \( x \):
Subtract \( 10x \) from both sides:
\[
7 = 10
\]
This statement is false, meaning that there are no values of \( x \) that satisfy the equation. Therefore, the answer is:
**B. no solution.**
