# How do you solve #2a-3=-11#?

First, identify what needs to be solved. In this case, we don't know the value of "a".

In equations like these, the element we don't know is usually written as "x", but it doesn't have to be that. In fact, you can use just about every letter you can think of, and the equations would be similar:

Here are some examples of similar equations, that are all solved the same way:

All the letters indicate a value we don't know.

I'll give one very good tip. It is usually best to "isolate" the part with the letter, in this case "a", first.

We can check to see if this is correct by replacing "a" with -4 in the original equation.

And there you have the solution :)

To solve 2a - 3 = -11, you would first add 3 to both sides of the equation to isolate the term with the variable. Then, you divide both sides by 2 to solve for a. So, ( a = \frac{-11 + 3}{2} ). Simplifying, you get ( a = -4 ).
