How do I answer this question I don’t understand it

Answer 1

Answer:

$u = -\dfrac{vx}{w}$

Step-by-step explanation:

You are allowed to multiply and divide both sides of an equation by the same non-zero number or non-zero variable. Do the appropriate operations to isolate the u.

$x = -\dfrac{1}{v}uw$

We are solving for u, so first, switch sides.

$-\dfrac{1}{v}uw = x$

Multiply both sides by v.

$-\dfrac{1}{v}uw \times v = x \times v$

$-uw = x \times v$

Divide both sides by -w.

$\dfrac{-uw}{-w} = \dfrac{xv}{-w}$

$u = -\dfrac{vx}{w}$
