It is a function, because they do not have a repeating number in the “Y” place (x,Y). If a set of orderd pairs had the y repeating, then it is not a function. The x can repeat, just not the y.
Peter: x
Arasoo: x+4
Ali: x-2
4+x+x+x-2=47
2+3x=47
3x=45
x=15
Peter: 15
Arasoo: 15+4= 19
Ali: 15-2 = 13
In order to isolate w, you would simply divide both sides by lh because divisionis the oppositeof multiplication which is currentlybeing done. After doing this, your answer is w = v/lh.
I hope this helps!
