I need help with my math algebra homework?!! Please???

Question

My question is:
How do you get y alone on the other side of this equation:

x=2y


i know it is already alone but i want it on the other side because i have to graph the x-intercept and slope.

please help.

plz and ty.

Answer 1

Always divide the whole equation by whatever is in front of the Y. (divide x=2y by 2)
therefore it would be
1/2X=Y
When there is only '1' in front of the y - whatever the number is infront of the x is the gradient/slope
Therefore the slope is 1/2
(rise/run = 1 up for every 2 accross)
The X intercept is the X value for whenever y=0
therefore:
1/2X=0
therefore X has to = 0 (x intercept is 0)

Answer 2

You have to divide both sides by 2.


Then it would be 1/2 x=y

Answer 3

In order to get rid of the 2, divide both sides by 2 because it does the opposite of the multiplying by 2 that is in the equation. Then you get y=x/2.

Answer 4

Divide both sides by 2. You will get 1/2x = y.

Answer 5

divide both sides by 2
y = 1/2 x

Answer 6

divide by 2

Answer 7

Well since you have an equal sign, you can just flip the equation around:
2y=x
Then divide by 2, and you have your isolated Y
y=x/2

Answer 8

Transpose y to the left side of the equation and x to the right side. In transposing, positive becomes negative and negative becomes positive. Let try.

x=2y transpose
-2y=-x devide both sides by -2
y = x/2 or 0.5x

Answer 9

multiply both sides by 1/2 so you get
(1/2)x = y

Answer 10

x=2y
divide both sides by 2

x/2=y
