Total price of an exercise book and a pen is 75 taka. If the price of the exercise book would be less by 5 taka and the price of the pen be more by 2 taka, price of the exercise book would be twice the price of the pen. What are the prices of the exercise book and the pen?

price of exercise book and a pen = 75 taka
let the price of exercise book be X
then, price of pen will be 75- X
A/q
x- 5 =2(75-x+2)
x -5 =2(77-x)
x-5=154-2x
X+2x =154+5
3x. =159
X. =159/3
x. =53
price of exercise book = 53 taka
price of pen = 75-x
=75-53
=22 taka
check by putting values of x in equation
x-5 =2(75-x+2)
53- 5= 2(22 + 2)
48. = 2× 24
48. = 48
