Let, cost of 1 kendamas be x
And, cost of 1 yo-yos be y
ATQ,
3x + 5y = 180----(1)
x + 2y = 64----(2)
from equation (2),
x= 64 -2y
putting the value of x in equation (1):-
3(64-2y) + 5y = 180
=> 192 -6y +5y = 180
=> 192 -y = 180
=> y = 192-180
=> y = 12
putting the value of y, in equation (2):-
x + 2y=64
=>x+2(12)=64
=>x+24=64
=>x=64-24
=>x=40
•°• x=40, y =12
Hence, cost of 1 kendama is $40
