Step-by-step explanation:
The given equation is:
![3x^2+3y^2=75](https://tex.z-dn.net/?f=3x%5E2%2B3y%5E2%3D75)
We divide through by 3 to obtain;
![x^2+y^2=25](https://tex.z-dn.net/?f=x%5E2%2By%5E2%3D25)
This is rewritten as:
![x^2+y^2=5^2](https://tex.z-dn.net/?f=x%5E2%2By%5E2%3D5%5E2)
This is the equation of a circle centered at the origin with radius 5 units.
In general, the statement 'a is subtracted from b' is written as
![b-a](https://tex.z-dn.net/?f=b-a)
Therefore, 'A number is subtracted from 2' is written as,
![2-x](https://tex.z-dn.net/?f=2-x)
The answer is 2-x
Im assuming the comma means equal?
68x - 136 =2380
Add 136 on both sides
68x= 2516
Divide 68 on both sides
X=36
