6-x=2x+9

If you are to solve the equation for x, first try to get the variable on one side of the equation.

Let's subtract 2x from both sides to start (whatever operation you do to one side of an equation you must do to the other side as well):

6 - x - 2x = 2x - 2x + 9

6 - 3x = 9

Now let's subtract 6 from both sides:

6 - 6 - 3x = 9 - 6

-3x = 3

Divide both sides by -3 to get x by itself and solve the equation:

-3x/-3 = 3/-3

x = -1

Does this check with the original equation? Substitute -1 for x and see if it checks out. It always helps to check your work!

I hope this will help.

THANK YOU SO MUCH! that helps me alot!

You're welcome! I'm glad I could help you. Remember, when solving equations, it's important to perform the same operation on both sides of the equation in order to maintain equality. Checking your work is also a good practice to make sure you haven't made any mistakes. If you have any more questions, feel free to ask!
