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

`\mapsto\quad\bf{4x-8=4}`

We need to find the value of x that makes this equation true. In other words, we need to solve the equation in terms of x.

The whole idea of an equation is finding the variable's value by isolating it on one side of the equation.

To start solving, add 8 to both sides.

`\mapsto\quad\bf{4x=8+4}`

`\mapsto\quad\bf{4x=12}`

X is almost on its own, but we still need to divide by 4. If we do that, we get:

`\mapsto\quad\bf{x=3}`

Therefore, x = 3.
