The number of students in the psychologhy class is 34 fewer than the number of students in world history. The total enrollment for the two classes is 134 students How many stduents are in each class.
Let w=students in world history
p=w-34; is number of students in psychologhy
So our equation would be;
(w-34)+w=134
Add like terms;
2w-34=134
Ass 34 to both sides;
2w-34+34=134+34
2w=168
Divide both sides by 2;
2w%2F2=168%2F2
w=84
Now we now the number of students in world history, and the number of students in psychology is 34 less.
p= 84-34=50
Hope you get it
