x = 5 rupees
Answer:
Step-by-step explanation:
Let coffee packets be c
Let tea packets be t
Statements are
3c + 2t = £23
1c + 4t + £21
Let us find the cost of t
First, put the c part the same therefore we must multiply the second statement by 3.
(1c + 4t = £21) = (4c + 12t = £63)
Next we cancel out so 3c cancel each other out therefore we are left with 10t = £40
10t = £40
t = 40/10 = £4
To find c we can do it two ways, do the process again but for c or substituting. Let us use substituting.
3c + 2t = 3c + £8 = £21
£21 - £8 = 3c
3c = £13
c = 13/31 = £4.33
t = £4
c = £4.33
