Answer:
Heya,
Here is the answer:-
Let,
> 5 rupee coin= x
> 2 rupee coin= 80-x [total no. of coins is Rs.80]
Equation:-
2(80-x)+5x= 232 [multiply 2*80 & 2*x]
=> 160-2x+5x= 232 [subtract -2x+3x]
=> 160+3x= 232 [shift +160 to the opposite side]
=> 3x= 232-160
=> 3x= 72
=> x= 72/3 [when 3 shifted to opposite side it becomes division]
=> x= 24
Which means 5 rupee coined will be 24 in number.
Hope my answer helps you :)
