Answer:
Both are equal
Step-by-step explanation:
Answer:
Step-by-step explanation:
First write the question as an equation
x+y = -5
2x+y = -2
From the given equations, we can create a third one.
x+y+2x+y = -7 or 3x+2y = -7
Use trial and error method for the possible values x and y
We know that at least one of these two have to be negative.
x can be 1, in which case y has to be 5.
Check this for
x+y ≠ -5
x can be -1
Try another one where x = -1 and y has to equal -2
Check this
X
x+y = -5
but,
2x+y ≠ -2
Another one,
Answer:
Step-by-step explanation:
12 x + 4 y = 42 .............1
16 x + 8 y = 64 .............2
Eliminate y
multiply (1)by -2
Multiply (2) by 1
-24 x -8 y = -84
16 x 8 y = 64
Add the two equations
-8 x = -20
X times S = $27. X is the cost of the large sacks and S is the amount of sacks. Once they are multiplied it should equal $27. If this is incorrect please let me know so I can try and correct mistakes made.
First, add 2x on both sides. then add 29 on both sides. you want to remove the negatives when you're doing this. now you have 7x equals 56. now you divide 7 on both sides. you want to do this because your isolating the variable. now to get x equals 8.
