Solve the following by any method:
{x = 9/4y + 7
{4x - 9y = 30
Is the system inconsistent, or are the equations dependent, or is the answer an ordered pair?
------------------------
Multiply thru the 1st equation by 4 and leave the 2nd equation unchanged.
4x = 9y + 28
4x - 9y = 30
------------------
Rearrange:
4x - 9y = 28
4x - 9y = 30
------------------
Subtract:
0 = 2
----------
No solution; lines parallel; system inconsistent
