If x and y are integers and 2x–y= 11, then 4x+ y CANNOT be  Choose the correct answer: A) –5 B) 1 C) 13 D) 17 E) 55
2x-y=11   2x=11+y   4x=22+2y   now we need to check the value of 4x+4 =&gt; 22+2y+y=22+3y   hence 22+3y=value(in the options)   so y=value-22/3   so checking the options only 17 is unfit   ANSWER:17
<result>D</result>
If x and y are integers and 2x–y= 11, then 4x+ y CANNOT be
