Answer:
Is there a x somewhere or is that litteraly how the equation is?
 If so, -7 multiplied by 2 is -14,
 -1 times -7 is 7, 
add it together and you get 
-7=28, 
you could add 7 to both sides or subtract 28 from both sides and you'll get either 0=35 or -35=0 
which would make the solution false since both sides are not the same
