Problem 3.1a:
Step 3:
Step 4:
The answers are and x=1. However these answers may
not be the solutions to the original equation. You must check your answers.
Step 5:
Since the left side of the original equation after we substituted the value
1 for, the solution x=1 is valid

Step 2:
Check the solution by substituting in the
original equation for x. If the left side of the equation equals the right
side of the equation after the substitution, you have found the correct
answer.
Since the left side of the original equation after we substituted the value
for, the solution is valid
Check the solution x = 1 by substituting 1 in the original equation for x.
If the left side of the equation equals the right side of the equation after
the substitution, you have found the correct answer.
You can also check your answer by
graphing (the left side of the original
equation minus the right side of the original equation). You will note that
the two x-intercepts on the graph are located at and 1
