Perhaps it is best to think of "x" as something tangible in real life. Consider x as an orange.
On the left-hand side of the equation you have 1 + 7 oranges. On the right hand side you have 8 oranges. Does 8 = 8? Yes, always. So we will say the solution is x such that x is contained in all real numbers.
