Question

X+y=-7 . how do you answere the question????

how do you solve it.

Answer 1

`x=-7-y, y=-7-x`

Explanation:

Since we don't have the values for the variables, we can only solve this equation in terms of the respective variable. For instance:

We can subtract `y` from both sides to solve for `x`. We get:

`x=-7-y`

Similarly, from the original equation `x+y=-7`, we can subtract `x` from both sides to solve for `y`. We get:

`y=-7-x`

This is the only thing we can do to this equation, since we don't have any value for `x` or `y` to plug in.
