Question

PLEEZE HELP WILL FAN AND MEDAL !!!!!
Two systems of equations are shown below:

System A
System B
2x + y = 5
-10x + 19y = -1
-4x + 6y = -2
-4x + 6y = -2

Which of the following statements is correct about the two systems of equations?

Answer 1

options
They will have the same solutions because the first equation of System B is obtained by adding the first equation of System A to 2 times the second equation of System A.
They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 3 times the second equation of System A.
The value of x for System B will be -5 times the value of x for System A because the coefficient of x in the first equation of System B is -5 times the coefficient of x in the first equation of System A.
The value of x for System A will be equal to the value of y for System B because the first equation of System B is obtained by adding -12 to the first equation of System A and the second equations are identical.

Answer 4

I assume this is system A:
2x + y = 5
-10x + 19y = -1

and that this is system B:
-4x + 6y = -2
-4x + 6y = -2

Answer 5

I see immediately that System B presents two identical equations. What does this mean in terms of the math involved?

Answer 6

Regarding System A:
2x + y = 5
-10x + 19y = -1

Why not actually solve this system as a way to identifying the correct answer?
Hint: multiply the first equation (all of it) by 5.

Then add this result to the 2nd equation and solve for y.

Answer 7

System A
2x + y = 5
-4x + 6y = -2
System B
-10x + 19y = -1
-4+ 6y = -2

Sorry, I don't follow what you've shared.

Please verify this:

System A is as follows:

2x + y = 5
-10x + 19y = -1

If so, mult. the first equation by 5 and solve the resulting system.

sorry, Layla, I'd like to help, but OpenStudy tells me you're "just looking around."
