How do you solve 7 plus 2x equals 11 plus x?

Answer 1

7 + 2x = 11 + x

Combine like terms by subtracting the 7 from both sides.

7 + 2x = 11 + x

-7 -7

This will leave you with 2x = 4 + x. Again, combine like terms, this time subtracting the x from both sides.

2x = 4 + x

-x -x

This will now leave you with 1x = 4. 1x and x are equivalent, so you can just forget about the one, leaving you with x = 4 as your final answer.

Hope this helped.
