what is the solution to these two equations, like how do I find the cost for each variable for 1 unit? Like what is 1c equal to and what is 1d equal to, much thanks for anyone who answers!
3c+5d=$22.75
2c+3d=$14.25
3c + 5d = 22.75 ---> x -2 ---> -6c - 10d = -45.50
2c + 3d = 14.25 ---> x 3 ---> 6c + 9d = 42.75
Adding down the columns: -d = -2.75 ---> d = 2.75
Substituting: 3c + 5(2.75) = 22.75 ---> 3c + 13.75 = 22.75 ---> 3c = 9.00 ---> c = 3.00
