Let's solve the problem given to us today! The problem is the following:

`\mapsto\quad\textbf{2 less than 4 times a number is 10}`

We need to write this as an equation and solve.

First, pick a letter to represent the unknown number. Then, set up the equation, and solve.

I'll choose g for my number.

Then, 2 less than 4 times g => 4g - 2.

This expression equals 10: => 4g - 2 = 10

Now, in order to solve for g, we add 2 to both sides:

4g = 10 + 2

4g = 12

g = 3

Therefore, g = 3.
