No solution... if you solve for x, than the answer would be N.S.
because....
x^2+7=0,
First, you isolate x by subtracting 7 from both sides.
x^2 = -7
then you square root both sides, to get rid of the '^2' but since your dealing with a negative number, (-7), it isn't possible to find the square root. Thus, making the answer automatically NO SOLUTION
