Answer:
![y=\frac{7}{24}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B7%7D%7B24%7D)
Step-by-step explanation:
24y = 7
Our primary objective here is to get y on it's own side, without any numbers attached.
Since a 24 is attached to the y, we have to divide the 24y by 24.
![24y=7](https://tex.z-dn.net/?f=24y%3D7)
![\frac{24y}{24} = \frac{7}{24}](https://tex.z-dn.net/?f=%5Cfrac%7B24y%7D%7B24%7D%20%3D%20%5Cfrac%7B7%7D%7B24%7D)
Remember that whatever we do to one side, we MUST do to the other.
![y=\frac{7}{24}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B7%7D%7B24%7D)
Since
can't be simplified, that would be our answer.

Answer:
7z -3x -3 is the solution to the equation
Step-by-step explanation:
7z -5 -3x +2
7z -3x -5+2
7z -3x -3
Solve simultaneously.
4x - y = 8
6x + y = 2
Multiply top equation by 6, and bottom equation by 4, to eliminate x, so that we can find y.
~
24x - 6y = 48
24x - 4y = 8
Subtract top from bottom to form one equation.
~
-2y = 40
Therefore y is 20.
Put y back in to an equation, such as 4x - y = 8.
~
4x - 20 = 8
4x = 28
x = 7
