Last week, we talked about systems of linear equations. There are two ways of solving systems: substitution and elimination. Either way, the goal is to convert the new problem (a system of two equations with two unknowns) into an old problem (one single linear equation with one unknown variable).
Next week, we will have our second test on linear equations, linear inequalities and linear systems. Please practice by reviewing your homework and doing the practice test. Email me if you have any questions, or meet up with me on Monday!
On Thursday, we will make the connection between algebra and geometry by introducing the coordinate plane. By then, we can talk about what linear equations, inequalities and systems mean: they are all related to the geometric object called line (therefore linear).
There is no homework due next week, but review to study for the test!
Alright, that’s it for now. Hope you have a good long weekend, let me know if you have any questions!
