Answer 2

Answer:

Option (A) 7x is correct.

Step-by-step explanation:

The given equation is:

$(4x-6)+(3x+6)$

Simplifying the above given equation, we get

$(4x-6)+3x+6$

⇒$4x-6+3x+6$

Rearranging the like terms and then simplifying the equation,

⇒$4x+3x-6+6$

⇒$7x$

which is the required simplified form.

Thus, option A that is 7x is correct.
