Question

5 pencils and 3 pens cost £11 4 pencils 6 pens cost £16 find cost of pen and pencil

Answer 1

Answer:

Pencil is £1 and the pen is £2

Step-by-step explanation:

Let pencil be p and let pen be f.

5p + 3f = 11

4p + 6f = 16

the top one multiplies by two:

10p + 6f = 22

4p + 6f = 16    subtract

6p = £6

pencil = £1

Then you substitute the value of pencil into equation and find the value of the pen.

cost of one pencil= Rs. x

cost of 5 pencil = 5x

similarly cost of 3pen =3y.
