if you enter 77 and 6 was taken off it would be 71 so 71
B, 71
I dunno

The three types of solution sets:
A system of linear equations can have no solution, a unique solution or infinitely many solutions.
A system has no solution if the equations are inconsistent, they are contradictory. for example 2x+3y=10, 2x+3y=12 has no solution. is the rref form of the matrix for this system.
