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.

this is answer of 144 cubic meters

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
