The solution to the system of equations is:

Solution

It seems like there might be a typo in your third equation. Specifically, \operatorname{coz} is unclear. I’m going to assume that you intended to write z. If that’s not the case, please let me know!
Given the system of equations:
Let’s solve for , , and .

Step 1: Simplify the First Equation

Start with the first equation:
Subtract 28 from both sides:
Solve for :

Step 2: Substitute into the Third Equation

Use Equation 4 in the third equation:
Substitute :
Combine like terms:
Add 4 to both sides:
Solve for :

Step 3: Substitute and into the Second Equation

Use Equations 4 and 5 in the second equation:
Substitute and :
Expand the terms:
Combine like terms:
Subtract 40 from both sides:
Divide by 16:

Step 4: Find and

Now, substitute back into Equation 5 to find :
Next, substitute into Equation 4 to find :

Solution Summary

If the third equation was intended to be different (for example, involving a trigonometric function like ), please provide the correct equation so I can assist you accordingly.

To solve this system of equations, you might want to start with the first equation: . Rearranging gives you . Next, substitute into the other equations to simplify them.
When you tackle the second equation with the value of substituted, you can reduce the number of variables and work towards finding values for , , and . Remember that isolating a variable in one equation can really help illuminate the relationships between them!
Additionally, always watch out for arithmetic mishaps! One common mistake is not balancing the equations after substituting a variable. Keep your calculations tidy! A small error can snowball into a big problem later, so double-check your work as you go along.
