Page 2: Solving Systems of Equations
This page covers two main methods for solving system of equations: substitution and elimination, providing detailed explanations of each approach.
Definition: Substitution method involves solving one equation for a variable and inserting that expression into the other equation to solve the system.
Highlight: When solving a system with two variables, the solution should be written as an ordered pair, following standard mathematical convention.
Example: The elimination method involves combining equations to create new equations with fewer variables, making the system easier to solve.
Vocabulary: Key terms for solving systems:
- Substitution: replacing variables with equivalent expressions
- Elimination: combining equations to remove variables
Quote: "When using elimination, look for the easiest variables to eliminate first."
Highlight: The elimination method is particularly effective for solving nonlinear equations, but should be used strategically rather than arbitrarily eliminating variables.

Page 1: Understanding Inequalities and Their Properties
This page introduces fundamental concepts of solving inequalities algebra 1 and explains key notation systems. The isolation method is presented as the primary approach for solving both equations and inequalities.
Definition: Strict inequalities indicate that two sides cannot be equal, while non-strict inequalities allow the sides to be equal.
Example: When solving an equation like 5r-2=10-r, you can verify the solution by substituting it back into the original equation:
- 6r-2=10
- r=2
Highlight: When multiplying or dividing an inequality by a negative number, you must reverse the direction of the inequality sign - this is a crucial solving inequalities rule.
Vocabulary: Interval notation components:
- () indicates values not included
- [] indicates values are included
- E represents "is in"
- -∞ represents negative infinity
- +∞ represents positive infinity
- R represents all real numbers
Example: Interval notation examples:
- TE[3,5) means 3≤t<5
- TE(4,∞) means t>4

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
