Question

How do you do
y=x-v/b

Answer 1

for what variable?

Answer 2

For x

Answer 3

Is the equation

\[\Large y = \frac{x-v}{b}\]

OR

\[\Large y = x-\frac{v}{b}\]

??

Answer 4

the first one

Answer 5

your first step is to multiply both sides by 'b'

Answer 6

what do you get when you do this?

Answer 7

But i thought you cant multiply a different variable with another

Answer 8

you can, there's no rule that says you can't

Answer 9

x times y is just xy (sure we can't find the numeric value of that, but we can just say it's xy)

Answer 10

Im confused, so like you multiply b by x and b by v?

Answer 11

you just multiply both sides by 'b' to get

\[\Large y = \frac{x-v}{b}\]

\[\Large yb = x-v\]

what's next?

Answer 12

oh, um i really don't know, my teacher didn't really explain this to us. Don't you just leave the problem like that since you cant do anything else?

Answer 13

no, you can add 'v' to both sides and this completely isolates x

Answer 14

\[\Large yb = x-v\]

\[\Large yb+v = x-v+v\]

\[\Large yb+v = x\]

\[\Large x = yb+v\]

Answer 15

and now you're done

Answer 16

Ohhhh, Thank you very much that was helpful
