Now, this is not a hard question. However, we are going to use it to introduce some of the basics of Desmos.

To solve for x , using Desmos, enter the equation into cell 1. (To enter an exponent, press shift-6 first.)

This is the line x = 6. (Every x -value on this line is equal to 6.)

Notice the red vertical line? It’s the graph of the line x = 6, meaning x does not vary. We’re looking for x ! Therefore, x equals 6.

Don’t believe it? Use Desmos to check it! Does =12 ?

Yes!

When x or y are relatively small, what you need to see is … well, easy to see. But when x and y are large, you may need to do a little searching to see what you need to see.
