Question 23966
For the second equation, add _2x to each side to get the equations in standard form:


x+y= 16
2x + 2y = 2


Multiply both sides of the first equation by -2 in order to eliminate the x coefficients, which by the way will also eliminate the y coefficients:
-2(x+y)= -2*16
2x + 2y = *2


-2x-2y = -32
2+2y= 2
0=-30


NO SOLUTION!  Therefore the lines are parallel!!
