7x

answer is 7x

Answer 2

Option (A) 7x is correct.

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.
