$\qquad$ ☀️
$\pink{\bf{ {m = \: \:4.4 }}}$

We are given –

That means –

Let's substitute the values of x & y in the given equation.

$\qquad$
$\pink{\twoheadrightarrow\bf 5x -y = 20 }$

$\qquad$
$\twoheadrightarrow\sf 5 * m - 2 =20$

$\qquad$
$\twoheadrightarrow\sf 5m =20+ 2$

$\qquad$
$\twoheadrightarrow\sf 5m = 22$

$\qquad$
$\twoheadrightarrow\sf m = (22)/(5)$

$\qquad$
$\twoheadrightarrow\sf m =\cancel{ (22)/(5) }$

$\qquad$
$\pink{\twoheadrightarrow\bf m = 4.4}$
