State whether the system is inconsistent, or consistent and dependent x-15y-33 Select the correct choice below and fill in any answer boxes in your choice. OA. The solutions/ .(simplify your answer. Typean ordered par.) B There are infinitely many solutions. ° C. There is no solution. Which of the following best describes the system of equations? O consistent and dependent O inconsistent

Explanation / Answer

9x - 15y = -33

Or, 3x - 5y = -11

6x - 10y = -2

Or, 3x - 5y = -1

By subtracting the first equation from the second we will get

3x - 5y - (3x - 5y) = -11 - (-1)

Or, 3x - 5y - 3x + 5y = -10

Or, 0 = -10 (which is impossible)

So There is no solution of the system and it is inconsistent.
