Answer 2

let the cost of one pencil be Rs x
let the cost of one pen. ople Rs y
therefore, cost of 5 pencils will be 5x
""""""""""""""""""""""""7 pens will be 7 y
atq, 5x+7y=50 ------>(1)
similarly, 7x+5y=46--->(2)
multiply 1 eq by 7 and 2 eq by 5
35x+49y=350
35x+25y=230
(-) (-). (-)
24y=120
y=5
put y=5 in (1)

5x+7(5)=50
5x=50-35
5x=15
x=3
