Question

.If 5 pencils and 7 pens together cost Rs50, Where as 7 pencils and 5 pens

cost together Rs 46. Form Linear equations to represent this situation​

Answer 1

Answer:

5x+7y=50, 7x+5y=46

Step-by-step explanation:

Let pencil be x,

Let pen be y,

So based on first demand,

5 pencil + 7 pen =50

But pencil is x and pen is y,

So,

5x+7y=50

Now for another demand,

7 pencil + 5 pen =46

But pencil is x and pen is y,

So,

7x+5y=46

So, linear equations are,

5x+7y=50

7x+5y=46
