$x = 5/3$

Step 1) Isolate the $x$ term on one side of the equation while keeping the equation balanced:

$9x - 15 + 15 = 0 + 15$

$9x - 0 = 15$

$9x = 15$

Step 2) Solve for $x$ while keeping the equation balanced"

$(9x)/9 = 15/9$

$(cancel(9)x)/cancel(9) = (3*5)/(3*3)$

$x = (cancel(3)*5)/(cancel(3)*3)$

$x = 5/3$
