Answer:

6 ounces of red beads

6 ounces of gold beads

Step-by-step explanation:

x + y = 12

x + 3y = 24

We can solve this with substitution or elimination.  In this case, I would suggest elimination.  Subtract the first equation from the second:

2y = 12

y = 6

Plug back into either equation to find x.

x = 6
