A. The solution is x = 0
B. The solution is the ordered pair (4, 7)
C. There is no solution since 4=7 is a false statement.

Answer:

The answer is C. There is no solution since 4 = 7 is a false statement.

Explanation:

The given problem is 13 + 4x - 9 = 7x + 7 - 3x.

The simplified version of it is 4 + 4x = 4x + 7.

Taking away the 4x on either side will leave you with 4 = 7.

Therefore, the answer is C. There is no solution since 4 = 7 is a false statement.
