Let x be the number of people at University B
x + (x+3.5) = 9.5
2x +3.5 = 9.5
2x = 6
x = 3 million students at University B
x + 3.5 = 3 + 3.5 = 6.5 million students at University A
Answer:
75
Step-by-step explanation:
I have answered ur question
To find the answer,we can set up two equations:
Let the integer be x and y seperately,and x be the larger number:
x+y=74
y=74-x....(1)
x-2y=26...(2)
Put (1) into (2):
x-2(74-x)=26
x-148+2x=26
3x=26+148
x=174/3
x=58
Put the above answer into (1):
y=74-58
y=16
Therefore,the answer is x=58, y=16.
