im sorry Step-by-step explanation:
Answer:
The rate is 6 for all of them
Step-by-step explanation:
The rate would be the price for one taco, so you divide the cost by the number of tacos you're getting.
Get x on one side then you can use substitution
So, change x+3y=3 to x= -3y+3
Then plug in x to other equation to find y
2(-3y +3)-3y=-12
-6y + 6 -3y = -12
-9y = -18
Divide both sides by negative nine to find y
y = 2
Then plug in to original equation to find x
x + 3(2) = 3
x + 6 = 3
x = -3
So, y = 2 and x = -3
I'm not sure about the answer but you could try drawing it how it describes it. It may help you picture it better. Sorry I couldn't be any more help but that's what I would try
