ANSWER
B. No solutions
EXPLANATION
To find the solutions that the equation has, solve the equation by collecting like terms and simplifying:
[tex]\begin{gathered} 3x+2x-6=7+5x \\ 5x-5x=7+6 \\ 0=13 \end{gathered}[/tex]From the solution above, the two sides of the equation have different values.
Hence, there are no solutions for the given equation.
The correct option is option B.
