1.) Create a single variable linear equation that has no solution. Solve the equation algebraically to prove that it does not have a solution.

2.) Create a single variable linear equation that has one solution. Solve the equation algebraically to prove that there is one distinct solution for the equation.

Answer:

  1. x = x+1
  2. 0 = x+1
  3. x+1 = x+1

Explanation:

1. There will be no solution if the equation is a contradiction. Usually, it is something that can be reduced to 0 = 1.

If we choose to make our equation ...

x = x +1

Subtracting x from both sides of the equation gives ...

0 = 1

There is no value of the variable that will make this be true.

__

2. Something that reduces to x = c will have one solution. One such equation is ...

0 = x+1

x = -1 . . . . subtract 1 from both sides

__

3. Something that reduces to x = x will have an infinite number of solutions.

One such equation is ...

x+1 = x+1

Subtracting 1 from both sides gives ...

x = x . . . . true for all values of x
