Hi,

7x-8y=40

8y-7x=40



 7x-8y=40

-7x+8y=40   |Associatve Principle EQ 2

  0 ≠ 80  NO solution, inconsistent systems



A consistent system has at least one solution.

An inconsistent system has no solutions.

An independent system has exactly one solution.

A dependent system has infinitely many solutions.
