6x = 23
for this type of problem you have to get x, by itself meaning x on one side and the number on the other side.
x is being multiplied by 6 so to undo that you divide by 6, and what you do to one side you must always do to the other, so divide both sides by 6
6x/6 = 23/6
6/6 is just 1 so
x= 23/6 or 3.833
