first, you have to combine the 6x and the 10x you do this by subtracting 6x from each side. doing that you get.... -11=4x-51 then, you have to combine the -11 and the -51 you do this by adding 51 to each side. doing that you get.... 40=4x lastly, you need to divide each side by 4 to isolate the variable x. you get... x=10
