Solving Simple Linear Equations

Hello! Today we are going to solve three linear equations for the variable x. Let's work through them one by one.

Starting with the first equation: two x plus four equals twelve.

First, we subtract four from both sides of the equation.

Twelve minus four simplifies to eight.

Now, divide both sides by two, and we find that x equals four.

Moving on to the second equation: three x plus seven equals sixteen.

We isolate the term with x by subtracting seven from both sides.
