Joni should have multiplied by 1,000.
Step-by-step explanation:
Mass of the box = 67 decagrams
1 decagram = 1000 centigrams
So, 67 decagrams = 67 x 1000 centigrams
= 67000 centigrams
Joni should have multiplied by 1,000.

→ Use Elimination:
-9x + 3y = -6
-9x + 2y = -10
__________ ---
0 + y = 4
y = 4
→ Use substitution:
-9x + 3y = -6
-9x + 3(4) = -6
-9x + 12 = -6
-9x = -6 - 12
-9x = -18
x = -18/-9
x = 2
So the value of x = 2 and y = 4
I hope this helps...
