Question 187698
6y-x=-12
1/6x+y=3 
this is the another given! i try to solve it but the answer is undefind too
am i correct!?? 
---------------
6y-x=-12
1/6x+y=3 Assuming you mean x/6, and not 1/(6x), -->x + 6y = 18
x + 6y = 18
x - 6y = 12
--------------  Add the 2 eqns
2x = 30
x = 15
------
y = 3 - 15/6
y = 1/2
