When you study algebra, you see relationships in the form of graphs, tables, and equations. these relationships connect independent variables with dependent variables. you probably also use the word relationship in your own life. compare what the word relationship means in algebra and what it means in your life. how are the meanings similar, and how are they different?

Studying algebra means you study relations of the variables and the numbers. The equations that are used in this subject could represent real life phenomenon. Models that are established by scientists and mathematicians has its foundation not only in science but also in mathematics especially algebra. Models are used to predict values that are impossible to obtain through experiments. These are used to describe relationships between factors. Relationships are connections that exist between ideas, people or objects. Its definition in math is also applicable in real life. In real life, it usually represent the connection between people.

The answer is: y would equal 3 because if you simplify the equation then it would be y= 3x+9 and if you divide 3x and 9 by 3 it would equal 3. y= 3
