Question

Let f(x) = 3x + 2 and g(x) =6 x - 7 Find f (x)-g(x).

Answer 1

Hint:
f(x) - g(x) = (3x + 2) - (6x - 7)

Answer 2

(3x + 2) - (6x - 7)?

Answer 3

Yes, now finish simplifying

Answer 4

18x -21x 12x -14 6x -41x?

Answer 5

I have no idea how you got that, but that's not even close.

Answer 6

Keep in mind, there's a minus sign between the two expressions.

Answer 7

please help, I tried to cross multiply

Answer 8

You don't need to multiply anything. You need to SUBTRACT

Answer 9

Oh!

Answer 10

-1(6x-7)?

Answer 11

Not exactly. I don't know how you're getting that, but it isn't right. What's your reasoning behind getting that result?

Answer 12

instead of subtract I decided to multiply 6x-7 my -1 so that I could add

Answer 13

Okay, so finish simplifying

Answer 14

I just want you to post the final result

Answer 15

Or you can post all your steps all at once.

Answer 16

(3x + 2) + (-6x + 7)?

-3x=9?

Answer 17

Actually, there shouldn't be an equal sign there

Answer 18

And x=-3?

Answer 19

Yeah, that's what I mean. You have the correct numbers, but the expression is incorrect.

Answer 20

ops

Answer 21

so its just x,-3?

Answer 22

It's not -3x EQUAl 9, it's -3x PLUS 9

Answer 23

Oh! -3x+9

Answer 24

Thank you hero!

Answer 25

You are a math god!
