Hi Kim
First of all the order of operations requires we solve what's inside the parenthesis first. So we distribute the ngeative sign across what's in the parenthesis and we get:
2x-4+x (because of the negative sign iin front of the numbers inside the parenthesis we need to reverse their signs
Now, we put this back into the equation and we get:
2x-4+x=5
combine like terms
3x-4=5
isolate the variable x with its number on the left side by adding 4 to both sides of the equation:
3x=9
Isolate and solve for x by deviding both sides by 3.
Now, plug the final answer back into the equation ensuring it works.
Hope this helps. Have a great day.
