<PRE><B>Question 278284</B>
2x/3 + 3y/4   = 11/12
x/3   + 7y/18 = 1/2


8x+9y= 12*11/12

8x+9y=11----------------1


x/3 +7y/18 =1/2

6x+7y= 1/2*18

6x+7y=9-----------------2

Multipy equation 1 by 3 and equation 2 by 4


24x+27y=33
24x+28y=36

-y=-3

y=3

Subsyitute the value of y in equation 1 an you get x=-2
