Question

w=fx solve for x

Answer 1

divide by \(f\)

Answer 2

You want to get the x alone right? So you have to get the f on the other side. The opposite of multiplication is division so you can divide the f on both sides to solve for x.

Answer 3

you mean like x=f/w?

Answer 4

@Lasandra , well the w doesnt move.

w = f x
-- ---
f f

w = x
--
f

Answer 5

Does that make sense?

Answer 6

yes thanks a lot i have some more if you don't mind helping me.

Answer 7

@Lasandra , keep writing here

Answer 8

okay

Answer 9

g=f/x

Answer 10

@jackellyn

Answer 11

which variable are you solving for?

Answer 12

x @jackellyn

Answer 13

f
g= ---
x

Let's move the x by multiplying it by both sides

xg = f

How can we get rid of the g?

Answer 14

we could probably multiply both sides by g?

Answer 15

Well, g is already being multiplied by x so we need to do the opposite to move it to the other side. So we need to divide g on both sides.

Answer 16

okay well yeah we could i came up with x=f/g

Answer 17

exactly!

Answer 18

Yay :) ok next one is d=ax^2/2 (the^ means it the 2nd power)

Answer 19

for x?

Answer 20

yes for x

Answer 21

what do we need to move first?

Answer 22

i think the a?

Answer 23

You can't move the a until you move the 2 so multiply both sides by 2. Then divide by a on both sides, what is your answer?
