So to start you should get x and y on the same side and get the numbers on one side. Then you should cancel out a variable. Because both y’s are 1 and they are opposite charges they will both cancel out to 0. Then add what is remaining which is the 2x and the 3x and equal that to +9-4 which equals 5. You want x to be all by itself so you would divide both sides by 5 and get that x=1. Then you would just substitue and solve for y. Hope this helped!
Since this number ends with a .59, this means that we should round 156.59 to 157.00. But because we never use .00 unless we are dealing with money, it's just better to say 157 instead of 157.00.
Hope this helps!
