If 3x+4y=88 and 3x-4y=14, what is the value of x subs y?	Pick one
A) 17/4 B) 25/4 C) 27/4 D) 25/4 E) 19/4
Given 3x+4y=88 ---Eq 1   3x -4y =14 -- Eq 2   Sum both eqns we get 6x = 102 =&gt; x = 17   Sum 3x in eq 2 =&gt; 51 - 4y = 14.   =&gt; y= 37/4   Now XY = 14 - 37/4 = 19/4.   Option 19/4 is correct answer.
