Answer:
y=2
Step-by-step explanation:
First, you substitute x with 2.
3(2)-6y=(-6)
Then, you multiply:
6-6y=(-6)
Next, you subtract 6 from -6. So, the first 6 gets crossed out because of inverse of operation.
-6y=-12
Finally, you divide -6 to both sides of the equation to get y=2

Answer:
Step-by-step explanation:
Let n represent the number of necklaces Rosaria ordered. Then the total cost of the order is ...
10(120 -n) +11(n) = 1270
n = 70 . . . . . . . . . . . . . simplify, subtract 1200
120 -70 = 50 . . . . . . . the number of bracelets
Rosaria purchased 70 necklaces and 50 bracelets.
I think associative, because it is the same thing in a different order.
