• There is no flaw in Deshaun’s reasoning. Deshaun is correct.

• Deshaun was correct to add the exponents, but he needs to find the value of x before he can simplify.

Jenny is solving the linear equation 12 + 3x - 5 = 8x + 8 - 5x. Her final two steps are:

7 + 3x = 3x + 8

7 = 8

Select the statement that correctly interprets Jenny’s solution.

• The solution is x = 0.

• The solution is the ordered pair (7, 8).

• There is no solution since 7 = 8 is a false statement.

• There are infinitely many solutions since 7 = 8 is a false statement.
