Analyze Two Variable Equations

• The solution is x=0

• The solution is the ordered pair (-5,-5)

• There is no solution since -5=-5 is a true statement.

• There are infinitely many solutions since -5=-5 is a true statement.

• Luisa's conclusion is correct because 0=0 in Step 5 shows that the answer equals 0.

• Luisa's conclusion is correct because the x variable was canceled from both sides of the equation in step 4.

• Luisa's conclusion is incorrect because 0=0 in Step 5 indicates that there are infinitely many solutions.

• Luisa's conclusion is incorrect because 0=0 in Step 5 means that there are no real solutions.
