x + y = 12
Equation 2: Difference:
x - y = 4
Solution:
x + y = 12
x - y = 4
-------------
Add the two equations together:
2x = 16
Divide both sides by 2:
x = 8
Solve for y:
Use equation 1 substituting for x:
x + y = 12
8 + y = 12
Subtract 8 from both sides:
y = 4
Answer:
one number is 8 and the other number is 4.
8 + 4 = 12
8 - 4 = 4

Answer:
I'm not sure if you mean (2/3)x +6 or 2/(3x+6) so I'm going to answer (2/3)x+6.
Step-by-step explanation:
let's just make f(x)=y real quick.
Then,
1. Switch the x and y in the equation
So you would get x=(2/3)y+6
2. Solve for y
So you would get
x-6=2/3y
3(x-6)=2y
(3x-18)/2=y
3. Refine and State
So the answer is f(x)= (3x-18)/2
