The cost of a one pack of ballpoint pens is $3 and the cost of one pack of gel pens is $7.
Step-by-step explanation:
Let x be the cost of a one pack of ballpoint pens and y be the cost of one pack of gel pens.
Then by considering the given description in question , we have the following system of equations:-
Multiply equation (1) by 2 on both the sides , we get
Eliminate equation (2) from (3) , we get
Put y= 7 in (1), we get
Hence, the cost of a one pack of ballpoint pens is $3 and the cost of one pack of gel pens is $7.
