Number operation puzzle

Please substitute such numbers for x so that the indicated numerical operations are correct - first, and the last x must be identical. Thank you.

Example:
x: 2 = x -2
y: 5 = y + 7
z * 4 = z + 6

Final Answer:

x =  4
y =  -8.75
z =  2

Step-by-step explanation:

$$\begin{gathered} x:2=x-2 \\ 0.5x=2 \\ x=\frac{2}{0.5}=4 \\ x=4 \end{gathered}$$

y:5=y+7

0.8y = -7


y = -7/0.8 = -8.75

y = -35/4 = -8.75

Our simple equation calculator calculates it.

z·4=z+6

3z = 6


z = 6/3 = 2

z = 2
