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.
