How do you solve the system of equations algebraically #2x-2y+3z=6, 2x-3y+7z=-1, 4x-3y+2z=0#?
There are no solutions
The system is presented as thus:
We will pick two pairs of equatwins in the system, and use addition and subtraction to eliminate the same variable from both pairs. We will use A and B, and B and C, for this, eliminating x:
Note that the variable portion of B is a multiple of the same section in A, i.e.
Solutions will,only be present if 0 = 19. Because this is not the case, there are no solutions.
