Question

Is ( – 9, – 6) a solution to this system of equations? y= 1/3x – 3 y = – 1/3x –
5

Answer 1

Explanation:

Substitute the point (-9, -6) into the system of equations:

`- 6 = (1)/(3)( - 9) - 3`

`- 6 = - (1)/(3) ( - 9) - 5`

Simplify by multiplying and subtracting.

`- 6 = - 6`

Correct.

`- 6 = -8`

Incorrect.

(-9, -6) is not a solution of the system of equations.
