Do 4x+7=11x-9 subtract 4x to 11x so you get 7x. Now your left with 7=7x-9 then you add 9 to the 7 which is 16 and your answer is x=16/7
If it is a bunch of dots on a graph, then the answer will be the one that has two sets of dots on the same vertical line (the y axis). so if there are two dots right above and below eachother, that graph is the correct answer.
