Question

Which answer shows this equation in standard form?

7 – 3(x – y) = –5x + 2

Answer 1

Standard form is \(Ax + By = C\).

First distribute \(-3\) into the parenthesis.

\(7 - 3(x - y) = -5x + 2\)

\(7 - 3x + 3y = -5x + 2\)

Can you do the rest? @OGangsta

Answer 2

let me try

Answer 3

7-(-2)+3y=2???

Answer 4

No, first you what to subtract 7 to both sides..because you want to keep the regular whole numbers without variables to the right of the equal sign.

Answer 5

oh i subtracted -5x

Answer 6

You're actually supposed to add 5x..and I don't see any term with 'x' in \(7-(-2)+3y=2\).

Answer 7

thats what i have

Answer 8

I know..and I don't see any 'x' term in it..

Answer 9

\(7 - 3x + 3y = -5x + 2\)

Okay, now we subtract \(7\) to both sides:

\( \cancel{7 - 7} -3x + 3y = -5x + 2 - 7\)

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

Now, add \(5x\) to both sides.

Answer 10

8x+3y=5

Answer 11

-8

Answer 12

-8x+3y=-5

Answer 13

No, that's close \(3y\) and \(-5\) are correct..but \(5x + -3x\) isn't \(8x\) or \(-8x\), it's the same thing as \(5x - 3x\).

@OGangsta

Answer 14

so 2x

Answer 15

Yep, so what's your final answer going to be?

Answer 16

2x+3y=-5

Answer 17

Yep!

Answer 18

thank you
