How to solve 6x+5x-4=2x-8

Answers

Answer 1

Answer: 6x + 5x - 4 = 2x - 8
11x - 4 = 2x - 8
11x - 4 (-2x) = 2x - 8 (-2x)
9x - 4 = -8
9x - 4 (+4) = -8 (+4)
9x = -4
9x (/9) = -4 (/9)
x = $- (4)/(9)$

Answer 2

Answer: 6x+5x-4=2x-8~~~First we simplify(add 6x and 5x)
11x-4=2x-8~~~Now add 4 to both sides
+4 +4
11x=2x-4~~~~Remove 2x from both sides now.
-2x -2x
9x=-4~~~~Now divide by 9x
÷9x ÷9x

x= -4/9

Answers

Answer:

Yes, I cannot tell what it wants you to state if it is though.

Step-by-step explanation:

I am assuming you are familiar with coordinates representing x and y coordinates so (x,y). If this is unfamiliar let me know.

For a function, there cannot be a repeat of xs unless every one goes to the same y. So for instance if (3,4)(3,5) were in the list this would not be a function because 3 is used twice but goes to a different number each time.

If the list had (3,4) twice so (3,4)(3,4), that could still be a function.

In your list There are no repeating xs, so you don't even need to check. It is a function.
