Answer:

We conclude that the 12x is the required expression that is equivalent to 7x + 4x + x and has only one term.

Step-by-step explanation:

Given the expression

[tex]7x+4x+x[/tex]

The current expression has three terms such as 7x, 4x, and x.

The current expression can be further simplified such as

[tex]7x+4x+x[/tex]

Add similar elements:  [tex]7x+4x+x=12x[/tex]

[tex]=12x[/tex]

Thus, the given expression [tex]7x+4x+x[/tex] can be expressed as the only one term such as [tex]12x[/tex].

i.e. [tex]7x+4x+x=12x[/tex]

Therefore, we conclude that the 12x is the required expression that is equivalent to 7x + 4x + x and has only one term.
