Use simultaneous equations to solve the following. three kilograms of jam and two kilograms of butter cost $29 and six kilograms of jam and three kilograms of butter cost $54. find the cost of one kilogram of jam and one kilogram of butter.

The cost of 1kg jam is $7 and the cost of 1kg butter is $4

Step-by-step explanation:

Let jam = x

butter = y

3x + 2y = 29 (1)

6x + 3y = 54 (2)

(1)×2 ->

6x + 4y = 58 (3)

(3)-(2) ->

y = 4

suby=4into(2)

6x + 3(4) = 54

6x = 42

x = 7

(Correct me if i am wrong)

i suppose it should be (y=2x-5)
