Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
4/3x + 1/2y =4
2/3x - 7/12y=-3
--------------------------
Multiply thru the 1st equation by 6
Multiply thru the 2nd equation by 12
--------------------------
8x + 3y = 24
8x - 7y = -36
------------------------
Subtract the 2nd from the 1st to solve for "y":
10y = 60
y = 6
------------
Substitute into 8x + 3y = 24 to solve for "x":
8x + 18 = 24
8x = 6
x = 3/4
-----------------
Ans: (3/4 , 6)
