[tex]4 + x + x + 2x + 5 + 3 + x[/tex]
Combining like terms, we have
[tex] = x + x + 2x + x + 4 + 5 + 3[/tex]
Next, add them
[tex] = 5x + 12[/tex]
Therefore, ''[tex]\sf\pink{4 + x + x + 2x + 5 + 3 + x}[/tex]" is equivalent to "[tex]\sf\purple{5x\:+\:12}[/tex]."

Answer:
B. 5x + 12.
Step-by-step explanation:
[tex]4 + x + x + 2x + 5 + 3 + x = ?[/tex]
Whenever you see variables without a visible coefficient, imagine there is a '1' in front of the variable.
[tex]4 +(1)x+(1)x+2x+5+3+(1)x=?[/tex]
From here, you can combine like terms.
Remember, combine means to add.
Like terms are terms whose variables (such as x or y) with any exponents are the same (such as x² or y²).
[tex](1)x+(1)x+2x+(1)x=5x.[/tex]
[tex]4+5+3=12.[/tex]
[tex]4+(1)x+(1)x+2x+5+3+(1)x=5x+12.[/tex]
I, therefore believe 5x + 12 is equal to 4 + x + x + 2x + 5 + 3 + x.
