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:

2/3 is more then 1/2
I think it’s 1:40 am or 1:40 pm
Answer:
x=46
Step-by-step explanation:
subtract 13 from both sides
x=59-13=46
The factored version of the equation is (a-5) (a+4)
