First solve the equation for 3x
-3x+3y=12
3x=-57-6y
Now substitute the given value into the equation
-(-57-6y)+3y=12
Then solve for y
Y=-5
Then substitute the given value of y
3x=-57-6✖️(-5)
Now solve for x
X=-9
Ordered pairs
(X,Y)=(-9,-5)
Then you are left with your answer:
(-9,-5)

Answer:
thirty and six hundred fifty-nine thousandths
Step-by-step explanation:
Answer:
So we have 3 pounds of apples. 3 pounds= 6 dollars. This means for 1 pound, it costs 2 dollars. So since 1 pound is 2 dollars, take 10 pounds and multiply it by 2, you get 20 dollars. So the cost of 10 pounds is 20 dollars. If you wanna do it the short way, the cost is always twice the amount of the pounds.
