IF you mean 
, then the following would be a solution:
First add 16 to both sides of the equation:
Now divide both sides of the equation by 3:
Take the square root of both sides to solve for "X", or simply solve by inspection: "what number(s) can be squared to get 49?"
Answer: -7 and 7 So the smallest solution would be "-7"
