Question 4(multiple choice worth 1 points)
(04.03 mc)

two systems of equations are shown:

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?
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.
