  • Answer:

    Option (A) 7x is correct.

    Step-by-step explanation:

    The given equation is:

    [tex](4x-6)+(3x+6)[/tex]

    Simplifying the above given equation, we get

    [tex](4x-6)+3x+6[/tex]

    ⇒[tex]4x-6+3x+6[/tex]

    Rearranging the like terms and then simplifying the equation,

    ⇒[tex]4x+3x-6+6[/tex]

    ⇒[tex]7x[/tex]

    which is the required simplified form.

    Thus, option A that is 7x is correct.
