Example Question #465 : Algebra
If 
Four
Zero
Two
One
Three
Two
can be rewritten as
If 
Solve separately:
or
It is not necessary to solve these statements, as we can determine that the correct response is two solutions.
Example Question #31 : Absolute Value
Solve for 
To solve absolute value equations, we must set up two equations: one where the solution is negative, and one where the solution is positive.
Example Question #467 : Algebra
True or false: 
Statement 1:
Statement 2:
BOTH STATEMENTS TOGETHER do NOT provide sufficient information to answer the question.
STATEMENT 1 ALONE provides sufficient information to answer the question, but STATEMENT 2 ALONE does NOT provide sufficient information to answer the question.
BOTH STATEMENTS TOGETHER provide sufficient information to answer the question, but NEITHER STATEMENT ALONE provides sufficient information to answer the question.
EITHER STATEMENT ALONE provides sufficient information to answer the question.
STATEMENT 2 ALONE provides sufficient information to answer the question, but STATEMENT 1 ALONE does NOT provide sufficient information to answer the question.
STATEMENT 1 ALONE provides sufficient information to answer the question, but STATEMENT 2 ALONE does NOT provide sufficient information to answer the question.
Assume Statement 1 alone.
Therefore, 
Assume Statement 2 alone. The sign of

Example Question #461 : Algebra
How many values of
a true statement?
None
Two
One
Four
Three
Two
Therefore, if 
Either
The correct choice is therefore two.
Example Question #469 : Algebra
How many values of
a true statement?
Three
None
Four
Two
One
None
If the first equation is true, then
and
If the second equation is true, then
and
In each situation, the absolute value of an expression would be negative; since the absolute value of an expression cannot be negative, no solution is yielded.
