Answer:

Step-by-step explanation:
When we solve for an equation, our goal is to find the value of the variable. Any variable can be used, but for the time being let’s assume we use
.
We can algebraeically solve equations until we get the value of x - in which we will have x equal to something.
Say we have the equation
. Our goal is to find the value of
. <u>We can do this by getting x isolated on one side so we have something equal to x</u>.
We can subtract 5 from both sides and divide both sides by 5.

We now know the value of
since it’s on one side of the equation.
Hope this helped!
