Question 278284
2x/3 + 3y/4 = 11/12
x/3 + 7y/18 = 1/2
-------
Multiply thru 1st equation by 12
Multiply thru 2nd equation by 18
----------------------------------------
8x + 9y = 11
6x + 7y = 9
------------------------
Multiply thru 1st equation by 6
Multiply thru 2nd equation by 8
---------------------------------------
48x + 54y = 66
48x + 56y = 72
-----------------------
Subtract 1st from 2nd1st and solve for "y":
2y = 6
y = 3
---------
Substitute into 6x+7y = 9 to solve for "x":
6x + 7*3 = 9
6x = -12
x = -2
