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.
