Question

the cost of 3 coffee tins and 2 tea packets is Rs. 23.00 and that of one coffee tin and four tea packets of the same type is Rs. 21.00, then the cost of each is solution in step by step​

Answer 1

Answer:

Coffee = 5

tea = 4

Step-by-step explanation:

Let

X = coffee

Y = tea

first condition

3x + 2y = 23........(1)

second condition

x + 4y = 21..........(2)

then equation 1 multiple by 2

6x + 4y = 46.........(3)

substract equation (3) - (2)

6x + 4y = 46

- x + 4y = 21

= 5x = 25

X = 25÷5

# x = 5#

put X = 5 in equation 2

5 + 4y = 21

4y = 21-5

4y = 16

y = 16÷4

# Y = 4#
