Answer:
Step-by-step explanation:
3x+4=−y
3x+4+y=−y+y(Add y to both sides)
3x+y+4=0
3x+y+4+−3x=0+−3x(Add -3x to both sides)
y+4=−3x
y+4+−4=−3x+−4(Add -4 to both sides)
y=−3x−4
Step: Substitute−3x−4foryin2x+y=0:
2x+y=0
2x+−3x−4=0
−x−4=0(Simplify both sides of the equation)
−x−4+4=0+4(Add 4 to both sides)
−x=4
−x
−1
=
4
−1
(Divide both sides by -1)
x=−4
Step: Substitute−4forxiny=−3x−4:
y=−3x−4
y=(−3)(−4)−4
y=8(Simplify both sides of the equation)
Answer:
x=−4 and y=8

Answer:
042
Step-by-step explanation:
682 has one correct placement this is the 2 becuase if we look at the 206 one we can see that the 6 is wrongly placed and 614 has one number wrongly placed, so it means that 2 is in the correct spot in 682.
Next, we can look at 206 and since we know the 2 is one of the values and 6 isn't, that leaves the 0.
Finally, we can eliminate al values of 7, 3, 8 because they are not correct. This leaves us with either 1 or 4 as the remaining variables. We know that we need the middle value, so that eliminates the 1.
To clarify this more, the code is 042.
Based on clue #1 and #2, we can say that 6 is not the correct number.
Now we know that the unlock code does not contain 6 and based on clue #3, we know that 2 and 0 are correct numbers but in the wrong position. From clue #1, 2‘s position should be on the right. The code is ??2.
Based on clue #5, 0‘s position should be on the left. The code is 0?2.
We have to find the missing number in the middle position. Based on clue #2, the middle number has to be 4. It cannot be 1, as the statement says that the number is wrongly placed.
We are left with 042.
