Hello!
You can make two equations based on what you know
x + y = 50
5x + 3y = 190
Subtract y from both sides of the first equation
x = 50 - y
Put x into the second equation
5(50 - y) + 3y = 190
Distribute the 5
250 - 5y + 3y = 190
Combine like terms
250 - 2y = 190
Subtract 250 from both sides
-2y = -60
Divide both sides by -2
y = 30
Put y into the first equation
x + 30 = 50
Subtract 30 from both sides
x = 20

Answer:
30 bags
Step-by-step explanation:
Nc + Nd = 50
5Nc + 3Nd = 190
Multiply by -5 becomes:
-5Nc - 5Nd = -250
5Nc + 3Nd = 190
Equals:
-2Nd= -60
simplify:
-2Nd/-2 and -60/-2 = Nd= 30 bags
