In this problem why is the easiest to substitute.
Just set the equations equal to each other because they both equal y
-x + 4 = 2x - 8
(You want to get all the x's to one side so add x to each side)
4 = 3x - 8
(next add 8 to both sides)
12 = 3x
(lastly divide 3 from both sides)
4 = x
You have got your x so now it is time to find that y just replace x to either of the two equations
y = 2(4) -8 or y = -(4) + 4
y = 8 - 8 y = 0
y = 0
Final Answer: y=0, x=4

Answer:My answer is Temp-pH I
I don't know if it is right or not
can be factored into 
. To double-check, you can multiply the terms together again using FOIL: first, outside, inside, last.
(3x)(x) + (3x)(8) + (-1)(x) + (-1)(8)
3x² + 24x - x - 8
3x² + 23x - 8
Check.
Answer: Use the given functions to set up and simplify (f - g)(x). You should get 3x^2 +4x+2
