$x = 7$

First, subtract $10$ from each side of the equation to isolate the $x$ term and to keep the equation balanced:

$5x + 10 - 10 = 45 - 10$

$5x + 0 = 35$

$5x = 35$

Now, divide each side of the equation by $5$ to solve for $x$ while keeping the equation balanced:

$(5x)/5 = 35/5$

$(cancel(5)x)/cancel(5) = 7$

$x = 7$
