@dude

Answer 5

I need help please lol

Answer 6

You can graph this or just isolate y, which do you want to do?

Answer 7

isolate y..but how do we do that

Answer 8

Example for A:
\(5x+3y=4\)
Subtract 5x on both sides
\(3y=-5x+4\)
Divide by 3 on both sides
\(y=\large \frac{-5x+4}{3}\) or \(y=\large-\frac{5}{3}x+\frac{4}{3}\)

Answer 9

So its not A

Answer 10

Yep

Answer 11

So for B:
5x-3y= -4

add 5x from both sides?

Answer 12

Subtract, you want to do the opposite operation

Answer 13

but we're subtracting for b so dont we add since its the opposite operation?

Answer 14

5x is positive

So you want to subtract it

Answer 15

3y= -5x - 4?

like that

im usually bad at this lmao

Answer 16

Looks right, just remember to keep the sign of the 3y

Answer 17

\(-3y= -5x - 4\)

Answer 18

then what do I do?

Answer 19

Divide by -3 on both sides

Answer 20

-5x-4/3

Answer 21

\[\frac{ -5x-4 }{ 3 }\]

Answer 22

\(y=\frac{5}{3}x+\frac{4}{3}\)

Answer 23

So its not b either

Answer 24

Neh

Answer 25

Now C

Answer 26

4x+16y = -20

Subtract 4x from both sides

Answer 27

Yes

Answer 28

16y = 4x-(-20) im not sure

Answer 29

Close
\[16y=-4x-20\]

Answer 30

now divide both sides by 4?

Answer 31

By 16, youre trying to get y by itself

Answer 32

y = \[\frac{ -4-20 }{ 16 }\]

Answer 33

-24/16

Answer 34

-1.5

Answer 35

so not C

Answer 36

\(y=-\frac{1}{4}x-\frac{5}{4}\)

Answer 37

Yeh

Answer 38

\(6x+2y=-8\)
Subtract 6x on both sides
\(2y=-6x-8\)
Divide by 2 on both sides
\(y=-3x-4\)

Answer 39

Therefore D is your answer

Answer 40
