Hich equation can pair with x-y=-2 to create a consistent and dependent systems?

We can simplify each equation and find the solution.

6x + 2y = 15 can't be simplified further.

- 8x - 3y = 2 can't be simplified further.

4x - 4y = 6 on simplification gives 2x - 2y = 3 or x - y = 3/2

But, it does not coincide with the given equation.

- 3x + 3y = 6 on simplification gives x - y = - 2 coincides with the given equation.

Hence,  - 3x + 3y = 6 can pair with x - y = -2 to create a consistent and dependent system.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
