Solving Linear Equations
Keeping our Algebraic Balance in mind, it’s now time to solve linear equations.
Let’s look at our first example.
Solve x + 2 = -9 for x.
While we work on this problem it is important to keep the Algebraic Balance in mind. If we want to get x all by itself, we need to subtract 2 from both sides.
x + 2 – 2 = -9 – 2
x + 0 = -11
x = -11
