slove for x y=3x-9?

Question

please help me

Answer 1

y = 3x - 9

y + 9 = 3x - 9 + 9

y + 9 = 3x

y/3 + 9/3 = 3x/3

y/3 + 3 = x

Answer 2

slove for x ; y=3x-9?

3x =y +9, so x = (1/3)y +3 Answer.

Answer 3

y=3x-9
0=3x-9 set the Y to 0
9=3x add 9 to both sides
3=x divide both sides by 3
x= 3

Answer 4

y=3x-9
+9 +9 (first pass the nine to the other side addind both sides by nine so you can cancel out the nine on the right hand side
y+9=3x+9-9 you get then y+9=3x now divide both sides of the equation by three so you can cancel the three on the right side and keep only the x by itself
(y+9)/3=3x/3 so you get (y+9)/3=x that's your answer solved for x

Answer 5

Here it is step by step:

y=3x-9 (now add 9 to both sides)
y+9=3x (now divide both sides by 3)

(y+9)/3 = x or

1/3y + 3 = x

Answer 6

y= 3x -9 | plus 9
y + 9 = 3x | divided by 3
(y+9) / 3 = x

Answer 7

You can get answer by manually putting the value of x and y
like
let x=1, y=3-9=-6
x=2, y=(6-9)/2=-3/2
x=3, y=0 and so on.

Answer 8

As the equality is y = 3x - 9
then make the x as a subject and y become subject
y = 3x - 9
y + 9 = 3x
( y + 9 ) / 3 = x
an so x = ( y + 9 ) / 3 .................# that's the answer # :)

Answer 9

y=3x-9
so, y+9=3x
therefore, 3x=y+9
x=1/3(y+9)
x=1/3x+3

Answer 10

x= 1/3y+3
