  1. Step 1- Solve for one variable in at least one equation, if necessary. Step 2- Substitute the resulting expression into the other equation. Step 3- Solve that equation to get the value of the first variable. Step 4- Substitute that value into one of the original equations and solve. Step 5- Write the values from Steps 3 and 4 as an ordered pair ...

  6. Example 1: Each element of the domain is being traced to one and only element in the range. However, it is okay for two or more values in the domain to share a common value in the range. That is, even though the elements 5 and 10 in the domain share the same value of 2 in the range, this relation is still a function. Example 2:
