Question

form the pair of linear equations in the following Problems and their solutions graphically 5 pencils and 7 pens together cost rupees 15 where 7 pencils and 5 pens together cost rupees 46 find the cost of one pencil s and that of one pen graphically​

Answer 1

let the cost of pencil in both cases be x

so cost of pen s both cases be your

5x+7y=₹15

and

7x+5y=₹46

so

5x=15-7y

and

7x=46-5y

if you take any value for y in both the cases then u get coordinate for ur graph to plot

at least take the value of your three times in both cases

and where the lines interested in graph u get ur answer

mark it brainliest

Answer 2

ur answer is up dear copy it it's an easy one
