Question

6 pencil and 9 pens together cost 96 Rs 9 pencil and 5 pens cost 84 Rs Find the cost of 1 pencil and 1 pen

Answer 1

Answer:IF IT IS RIGHT PLEASE MARK BRAINLIEST  

Cost of 1 pencil = A

Cost of 1 pen = B

So,

6 A + 9 B = 96  ----------------1            x 9

9 A + 5 B = 84  ----------------2           x 6

Multiply 5 in 1 eq and 9 in 2 eq

 54 A + 81 B =  864

- 54 A - 30 B = -504

  51 B = 360

B = 7.0589 Rs

A = 5.41176 Rs
