Nylah Wilkinson · Answer 1

1) D

Inconsistent equations have no solutions and contain no further classes

2) C

The two equations are consistent and dependent so have an infinite number of solutions.

3) B

Linear equations have either 0, 1 or infinite solutions

4) C

The equations already are in a form in which upon addition, x is eliminated.
