To determine which of the terms will make the systems equivalent, we need to find the missing equation in System B.
The given equation in System A is 7x + 4y = -4. In order for System A and System B to be equivalent, the second equation in System B should have the same coefficients for x and y.
Let's examine the given equations in System B:
7x + 4y = -4
?
The equation 7x + 4y = -4 already has the same coefficients as the equation in System A. Therefore, the missing equation in System B will be the same equation: 7x + 4y = -4.
None of the provided answer choices match the equation 7x + 4y = -4. Therefore, the correct answer is none of the above.
System A:
7x+4y=-4
5x+8y=28
System B:
7x+4y=-4
?
Which of the following terms will make the systems equivalent?
a. -14x-8y=8
b. 12x+12y=24
c. -12x-12y=24
d. -14x-8=-8
