Hey

let the cost of each pencil be x and pen be y

5x + 7y = 50.......(1)

7x + 5y = 46.......(2)

(1) X 7

35x + 49y = 350.....(3)

(2) X 5

35x + 25y = 230......(4)

(3) - (4)

24y = 120

y = 120/24

y = 5

substitute y=5 in (1)

5x + 7(5) = 50

5x + 35 = 50

5x = 50 - 35

5x = 15

x = 15/5

x = 3

Therefore the cost of each pencil is 3 and pen is 5
