Thank you Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! solve each system of equations by elimination
3x+5y = -1
2x-4y = 3
-----------------
Multiply thru the 1st equation by 2
Multiply thru the 2nd equation by 3
==================
6x + 10y = -2
6x - 12y = 9
------
Subtract and solve for "y":
22y = -11
y = -1/2
-----
Solve for "x":
2x-4y = 3
2x -4(-1/2) = 9
2x + 2 = 9
2x = 7
x = 7/2
