Cross-multiply.

Explanation:

Solving an expression/equation with a variable implies we determine the value of said variable.

In order to solve this expression, we must apply a concept known as cross-multiplying.

Socratic

$\frac{32}{56} = \frac{4}{x}$ $32/56=4/x$

$32 x = (56) (4)$ $32x=(56)(4)$

$32 x = 224$ $32x=224$

$\frac{32 x}{32} = \frac{224}{32}$ $(32x)/32= 224/32$

$x = 7$ $x=7$

Therefore, $x = 7$ $x=7$ .

Hope this helps :)

Cross multiply
$32 x = 56 \times 4$ $32x=56xx4$
$32 x = 224$ $32x=224$
$x = \frac{224}{32}$ $x=224/32$
$x = 7$ $x=7$
