y=X^2-18

 since 18 doesn't contain the variable  add 18 to both sides to get

18+y = x^2

then take square root to get just x

so square root(18+y) = x

 for complete solution use both negative and positive answers so

x = - square root (18+y) & x = square root (18+y)

Answer:

x = (plus or minus) (sqrt) y+18
