Hello, my name is Stephen Kent! I will be your tutor.

/\[\frac{ 4 }{ 3 } = \frac{ x }{ 12 }\]
The first step to solving the equation is to cross-multiply all terms. Can you do that for me?

Answer 3

so is that 4*12 then 3*x ?

Answer 4

Correct! Can you write out the new equation?

Answer 5

isn't that the equation though?

Answer 6

Now. The new equation is:
\[48 = 3x\]

Answer 7

ohh. okay. so then x = 16 ?

Answer 8

Yup, that's correct!

Answer 9

so then how do i get the answer for this?
