Question

which of the following is not a solution to the equation -2x + 3y = 9A) (0, 3)B) (-6, -1)C) (-3 , 1)D (1 , -3

Answer 1

(1, -3) is not a solution of the equation

Explanation:

We have the following equation

`-2x+3y=9`

What we must do is replace the values, and if it is equal to 9, if it is a solution, if not 9, it is not a solution

`\begin{gathered} (0,3) \\ -2\cdot0+3\cdot3=9 \\ 9=9 \\ (-6,-1) \\ -2\cdot-6+3\cdot-1=9 \\ 9=9 \\ (-3,-1) \\ -2\cdot-3+3\cdot1=9 \\ 9=9 \\ (1,-3) \\ -2\cdot1+3\cdot-3=9 \\ -11\\e9 \end{gathered}`
