There are x apples in a box. If the same number of apples are added and 3 raw apples are removed, then 7 apples remain in the box. Then find the value of x.
a :
6
b :
10
c :
5
d :
4
Explanation :
The box initially contains x apples.
Put x more apples in it → total 2x).
Removed 3 raw apples from it → (2x - 3). Given Balance = 7
2x - 3 = 7
2x = 10
x = 5
Put x more apples in it → total 2x).
Removed 3 raw apples from it → (2x - 3). Given Balance = 7
2x - 3 = 7
2x = 10
x = 5
