Well you need to find the value of x. So this is what you do. You have to isolate the variable in other words it needs to be on one side of the equation. You would need to add 11 to both sides and you would get 13x= 9x -2. Then you do the same with 9x and subtract it from boths sides and end up with 4x= -2. You divide -2 by 4 and get -1/2 as your answer. So x= -1/2. I hope this helps love! :)
