Given : A shopkeeper sold 3 pencils and 4 pens to a customer for Rs.44.
A little later another customer purchased 6 pencils and 8 pens for Rs.90.
To Find : Form a pair of linear equations to represent this situation.
Solution:
Let say pencil cost = Rs x
and Pen cost = Rs y
shopkeeper sold 3 pencils and 4 pens to a customer for Rs.44.
=> 3x + 4y = 44
6 pencils and 8 pens for Rs.90.
=> 6x + 8y = 90
a pair of linear equations to represent this situation.
3x + 4y = 44
6x + 8y = 90
additional info : no solution exist for this linear pair of equation so can be mistake in data in Question
as 6x + 8y = 90 => 3x + 4y = 45
while another equation is 3x + 4y = 44
Hence no solution
