$x = 4$ $color(green)(x=4)$

Explanation:

If $y = 2 x - 3$ $color(red)(y) = 2color(blue)(x)-3$
then when $y = 5$ $color(red)(y)=color(red)(5)$
$XX 5 = 2 x - 3$ $color(white)("XX")color(red)(5)=2color(blue)(x)-3$

Adding $3$ $3$ to both sides
$XX 8 = 2 x$ $color(white)("XX")8=2color(blue)(x)$

Then dividing both sides by $2$ $2$
$XX 4 = x$ $color(white)("XX")4=color(blue)(x)$
or (equivalently)
$XX x = 4$ $color(white)("XX")color(blue)(x)=4$
