-2z - xy = z + 7
You are solving for x. Note the equal sign. What you do to one side, you do to the other. Isolate the x.
First, add 2z to both sides
-2z (+2z) - xy = z + 7 (+2z)
Simplify. Combine like terms
-xy = z + 2z + 7
-xy = 3z + 7
Completely isolate the x. Divide -y from both sides
(-xy)/-y = (3z + 7)/-y
x = (3z + 7)/-y
Simplify
z = (3z + 7)/(-y) is your answer
hope this helps

The area of the circle is 3.14 square millimeters
<h3>Calculating Area</h3>
From the question, we are to the area of the circle
The area of a circle can be determined by using the formula,
A = πr²
Where A is the area of the circle
and r is the radius of the circle
From the given information,
r = 1 mm
and π = 3.14
Putting the parameters into the equation, we get
A = 3.14 × 1²
A = 3.14 × 1
A = 3.14 mm²
Hence, the area of the circle is 3.14 square millimeters
