Question 319530: solve the following system of equations.if the system cannot be solved,state that it cannot be solved and explain why 3x-2y=4 2x-5y=21 Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! 3x-2y=4
2x-5y=21
-----------
6x - 4y = 8
6x -15y = 63
----------------------
Subtract 2nd from 1st to get:
11y = - 55
y = -5
------------------
Substitute into one of the equations and solve for "x":
