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
