Question

If y = 3 when x = 2. find x when y = 5.

Answer 1

Is this still the direct variation problem? We need an equation.

Answer 2

Yeah, but different WS.

"In Excersises 25-27, y varies directly as x

Answer 3

Awesome, then y=kx
y=3, x=2
3=2k

Answer 4

Oohhhhhhh. That makes sense.....-feels like an idiot-

Answer 5

After you find k, put it back into y=kx with y=5 and solve for x.
Not an idiot... you have to wait for that moment when it just clicks. ;)

Answer 6

Ok, thanks!
