Answer 2

Answer:

let the cost of pen be x

cost of pencils be y

Step-by-step explanation:

SOLUTION

BY FIRST CONDITION

x+y=55------1

BY SECOND CONDITION

x=2y----2

SUBSTITUTING 2 IN 1

x+y=55

2y+y=55

3y=55

y=55/3

y=18--------actual answer is 18.3333 but equating the number

SUBSTITUTE y=18 in 1

x+18=55

x=55-18

x=37
