3) they will have the same solution because the first equation of system B is obtained by adding the first equation of system a
to 4 times the second equation of system a
4) 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 -4 to the first equation of system a and the second equation are identical
