Answer 1

Hey there,

If 2x articles cost 5x+54 then the cost of one article=5x+54/2x

If x+2 articles cost 10x-4 then the cost of one article=10x-4/x+2

Now equating the price of one article since they both are same articles, we get-

5x+54/2x=10x-4/x+2
By cross multiplying, we get-
15x²-72x-108=0
So x=6,-36/30
Since articles cannot be negative,

Therefore x=6
