In a Single Displacement reaction, an element and a compound are reacting. In the end, the element has switched with one of the elements involved with the compound from the reactant side.

A + BC **→** B + AC

Zinc and Hydrogen Chloride react to form Zinc Chloride and Hydrogen.

Zn + 2HCl → ZnCl2 + H2

At first, the equation should look like this: Zn + HCL → ZnCl +H. Next it should be noted that Hydrogen is one of those diatomic elements that when by itself, is automatically H2. Since there is now two hydrogen on the right side, there needs to be two on the left side. Now there are two chlorines on the left side, so there should also be two chlorines on the right side. Now you are done.
