two systems of equations are shown below:
system a:
2x + y = 5
-4x + 6y = -2
system b:
-10x + 19y = -1
-4x + 6y = -2

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

a: 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.

b: 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.

c: 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.

d: 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.
