Question 150110: 3x-4y=1
2x-5y=3
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! 3x-4y=1
2x-5y=3
---------
Multiply thru 1st by 2 ; Multiply thru 2nd by 3:
---------
6x - 8y = 2
6x -15y = 9
--------------
Subtract 2nd from 1st:
7y = -7
y = -1
--------
Substitute into 2x-5y=3 to solve for "x":
2x -5*-1 = 3
2x = -2
x = -1
-------------
Solution: (-1,-1)
