Answer 2

It seems like you've provided two equations with two variables, x and y. To solve this system of equations, you can use the method of substitution or elimination. Let's use the elimination method in this case.

Here are the two equations:

1. 4y - x = -337
2. -x - y = 49

First, we can multiply the second equation by -1 to make it easier to add the equations together:

1. 4y - x = -337
2. x + y = -49

Now, you can add the two equations together to eliminate the x variable:

(4y - x) + (x + y) = (-337) + (-49)

The x term cancels out:

4y + y = -386

Now, combine the y terms:

5y = -386

To solve for y, divide both sides by 5:

y = -386 / 5 y = -77.2

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

4y - x = -337 4(-77.2) - x = -337

Simplify:

-308.8 - x = -337

Now, isolate x by adding 308.8 to both sides:

-x = -337 + 308.8 -x = -28.2

Multiply both sides by -1 to solve for x:

x = 28.2

So, the solution to the system of equations is:

x = 28.2 y = -77.2
