Answer:

(2, -6)

Explanation:

To solve this system of equations:

2x + 7y = -38

-5x - 8y = 38

We can use the method of elimination to eliminate one of the variables. We can do this by multiplying the first equation by 8 and the second equation by 7, which will give us:

16x + 56y = -304

-35x - 56y = 266

Adding these equations will eliminate the y variable and give us:

-19x = -38

Dividing both sides by -19 gives us:

x = 2

Now that we have the value of x, we can substitute it into either of the original equations to solve for y. Let's use the first equation:

2x + 7y = -38

2(2) + 7y = -38

4 + 7y = -38

Subtracting 4 from both sides gives us:

7y = -42

Dividing both sides by 7 gives us:

y = -6

Therefore, the solution to the system of equations is x = 2 and y = -6, or (2, -6) in coordinate form.
