The given equation is
![3z-19=173](https://tex.z-dn.net/?f=3z-19%3D173)
First, we add 19 on each side
![\begin{gathered} 3z-19+19=173+19 \\ 3z=192 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%203z-19%2B19%3D173%2B19%20%5C%5C%203z%3D192%20%5Cend%7Bgathered%7D)
Then, we divide the equation by 3
![\begin{gathered} \frac{3z}{3}=\frac{192}{3} \\ z=64 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7B3z%7D%7B3%7D%3D%5Cfrac%7B192%7D%7B3%7D%20%5C%5C%20z%3D64%20%5Cend%7Bgathered%7D)
<h2>Hence, z is equal to 64.</h2>
<h2> the answer isthe value of x=20°</h2>

Expressed in scientific notation the answer would be 3.05 X 10^6
Answer:
The first number = 8
The second number = 12
Step-by-step explanation:
let the given first number = x
And the given second number = y
Now, according to the question:
x = y - 4
2 y = 5x - 16
Now substitute the value of x in (2)
2 y = 5x - 16 ⇒ 2 y = 5(y -4) - 16
or, 2y = 5 y - 20 - 16
or, - 3 y = - 36
⇒ y = 36/3 = 12
So , the second number y = 12
and x = 12 - 4 = 12 - 4 = 8
Hence, the first number = 8
and the second number y = 12
