Step-by-step explanation:

To solve for "" in the equation: , we apply operations on both sides of the equality such that lead us to isolate the value we need to solve for (in our case ) on one side of the equal sign.

Let's start by "adding"  5 to both sides, so we eliminate it on the left, proceeding to isolate the term that contains :

now proceed to eliminate the factor "x" that multiplies "", by dividing both sides by "x":

has been isolated on one side of the equal sign, so this is the expression we got for it:
