This week in Pre-Calc 11 we reviewed systems and inequalities and how to solve them algebraically. I chose this topic because it is a skill that I particularly struggled with last year. Let’s try an example.

In this equation you might be panicking a bit because there is no = sign, but fear not the < and > symbols can be treated the same as an equal sign when isolating the variable. So now the first step we should do here is to expand our equation.

Then we move our variables together.

Now we isolate x and simplify and tadaa we did it!
