$\longrightarrow{\blue{B.\:5x\:+\:12}}$

$\large\mathfrak{{\pmb{\underline{\purple{Step-by-step\:explanation}}{\purple{:}}}}}$

$4 + x + x + 2x + 5 + 3 + x$

Combining like terms, we have

$= x + x + 2x + x + 4 + 5 + 3$

Next, add them

$= 5x + 12$

Therefore, '' $\sf\pink{4 + x + x + 2x + 5 + 3 + x}$ " is equivalent to " $\sf\purple{5x\:+\:12}$ ."
