Cd= x =5,96
Dvd=y
5x+2y=127,73
2y = 127,73 - 5 (5.96)
2y = 127,73 - 29.8
2y = 97.93
y = 97.93/2 = 48.965
x=5,96
y=48.965
6x+2y = 6(5,96) + 2(48.965) = 35.76 + 97.93 = 103.89
Final answer: 103.89
*i made it the much detailed possible as i don't know what your teacher asks of you so alot of it is unnecessary
