Answer 3

It seems like you've provided a system of equations with three variables, x, y, and z. Let's solve this system step by step.

The system of equations is:

1. 49 - 3x = 109y - 89
2. 5574 - 8z = 2

First, we can simplify equation (2): 5574 - 8z = 2

Subtract 5574 from both sides to isolate -8z: -8z = 2 - 5574

-8z = -5572

Now, divide both sides by -8 to solve for z: z = (-5572) / (-8)

z = 696.5

Now that we have found the value of z, let's substitute it back into equation (2) to check our solution: 5574 - 8z = 2 5574 - 8(696.5) = 2 5574 - 5572 = 2 2 = 2

The equation (2) holds true, which confirms that z = 696.5 is the correct solution for z.

Now, let's move on to equation (1): 49 - 3x = 109y - 89

Add 89 to both sides: 49 + 89 - 3x = 109y

138 - 3x = 109y

Now, we can isolate y by dividing both sides by 109: (138 - 3x) / 109 = y

So, y = (138 - 3x) / 109

You now have expressions for y and z in terms of x:

y = (138 - 3x) / 109 z = 696.5

These are the solutions to the system of equations. You can plug in any value for x, and you will be able to find the corresponding values for y and z.
