Question

a -3b = 4
a =b - 2

B. (-3,-1)
C. (-9,-7)
D. (-5,-3)

Answer 1

@pooja195

Answer 2

1) a -3b = 4
2) a =b - 2

Multiply equation 1) by -1 and
add -b to both sides of equation 2)

1) -a +3b =- 4
2) a -b = - 2

ADD both equations

2b = -6

Can you take it from there?

Answer 3

So A is not the answer

Answer 4

i really dont know how to do it

Answer 5

For one thing what does B = ?

Answer 6

3 ?

Answer 7

D for DEEZ NUTZ!!!! GODDEIMM!!!!

Answer 8

No because 2 * 3 =6
You need a value of B so that
2 * B = -6

Answer 9

Just Plug A In For X Values, And B In For The Y Values

Answer 10

chrisdbest what are you talking about?

Answer 11

im so confused

Answer 12

itsmee you almost have the answer
2 * B = -6
what is B?

Answer 13

itsmee - how mush algebra do you know?
2 * B = -6
If you can't solve the above equation, I don't think you are ready to be solving for 2 unknowns.

Answer 14

@wolf1728 I'm talking about the right answer without being too blunt about it.

Answer 15

I am not trying to give you a rough time.
Perhaps if your instructor knew your math experience you could get into a different class.

Answer 16

Okay Chris. Sorry.
I thought we weren't just supposed to "dish out" answers.
It helps if someone LEARNS a little. I don't think itsmee should even be taking a class like this.

Answer 17

Okay, I'll leave and "chrisdebest" can just dish out the answers.
See ya folks.
