April savings -- 2500
Salary -- 5000
May saving --- x
Amount spent in May = x + 4200
x + 4200 = 5000
x = 800
here is the answer.
lets say X is the saved money in May.
He spend 4200 more than X. It meant X+4200 is the money that he spent.
So, X + (X+4200) needs to be 5000.
Therefore, X=400. He saved 400 dollars in May
800
