3x - 7 + 7 = 12 + 7
3x = 19
3x/3 = 19/3
X = 19/3 = 6 1/3

Answer:
See below. The answer is incomplete, I couldn't post it.
Step-by-step explanation:
Considering a function
, it is said to be discontinuous when it has a hole or breaks, it means places where
cannot be evaluated. For example, when the denominator equals to 0, it is not defined.
A + B + C = 518 ft^3
A = 1/3B, or 3A = B
B = C
A + B + C = 518 ft^3
1/3B + B + B = 518
7/3B = 518
B = 518×3/7 = 222 ft^3
A = 1/3B = 1/3×222 = 74 ft^3
C = B = 222 ft^3
Answer:
![7y - 4x](https://tex.z-dn.net/?f=7y%20-%204x)
Step-by-step explanation:
![-3 (2x-y)+2y+2(x+y)\\](https://tex.z-dn.net/?f=-3%20%282x-y%29%2B2y%2B2%28x%2By%29%5C%5C)
Step 1: Open the brackets
![= -6x+3y +2y +2(x+y)\\=-6x +3y + 2y +2x + 2y](https://tex.z-dn.net/?f=%3D%20-6x%2B3y%20%2B2y%20%2B2%28x%2By%29%5C%5C%3D-6x%20%2B3y%20%2B%202y%20%2B2x%20%2B%202y)
Step 2: Bring the similar variables together
![=-6x +2x \ +3y + 2y + 2y](https://tex.z-dn.net/?f=%3D-6x%20%2B2x%20%5C%20%2B3y%20%2B%202y%20%2B%202y)
Step 3: Simplify by adding/subtracting the coefficients of the similar variables
![= - 4x +7y](https://tex.z-dn.net/?f=%3D%20-%204x%20%2B7y)
Step 4: Rearrange as required.
