$\large \mathfrak{Solution : }$

let's solve for x :

first step : adding 7 on both sides

next step : dividing by 9 on both sides :

$\dfrac{9x}{9} = \dfrac{17}{9}$ $x = \dfrac{17}{9}$

now, let's check for the solution by Plugging the value of x as 17 / 9 in the above equation.

$(9 \times \dfrac{17}{9} ) - 7 = 10$ 17 - 7 = 10

we can see that the LHS = RHS, therefore our value for x is correct. i.e 17 / 9

First you arrange them by least to greatest then because u would have 2 numbers as a median you add them then divide by 2
