Question

Which answer shows this equation in standard form?



6 – 2(x – y) = –3x + 5

A.x + 2y = –1
B.x + 2y = 1
C.x – 2y = 1
D.–5x + 2y = –1

Answer 1

@paki

Answer 2

the first thing i did was take away the parenthesis

Answer 3

first release the parantheses: 2(x-y)=2x-2y
now -(2x-2y) equals 2y-2x

So 6 - 2(x-y) will be equal to 6 + 2y - 2x

Answer 4

then i got 6-2x-2y=-3x+5

Answer 5

yeah i did that

Answer 6

standard form: Ax + By = C

Answer 7

now here is your equation
6+2y-2x=-3x+5
add 2x to both sides:
6+2y-2x+2x=-3x+2x+5
Simplify: 6+2y=5-x
subtract 6 from both sides:
6-6+2y=5-x-6
You will get: 2y=-x-1
Divide both sides by 2: y=(-x-1)/2 or y=-(x+1)/2

Answer 8

Thx jhanny i knew that :)

Answer 9

oops, sorry then @Jhannybean and @pinklion23

Answer 10

?

Answer 11

jhannybean what do you think

Answer 12

\[6 – 2(x – y) = –3x + 5\]\[6-2x+2y= -3x+5\]\[(3-2)x +2y = 5-6\]Simplify.

Answer 13

ok

Answer 14

ok, I will finish this equation.
here is your equation:
6+2y-2x=-3x+5
add 3x to both sides: 6+2y-2x+3x=-3x+3x+5
Simplify: 6+2y+x=5
Subtract 6 from both sides: 6+2y+x-6=5-6
2y+x=-1

Answer 15

\[x+2y=-1\]

Answer 16

yes. that's right

Answer 17

A is my answer then

Answer 18

hey great you guys gave medals to each other

Answer 19
