 Question 347190: I want to create a system of linear equations from my own life, it can be anything used on a daily basis. Keep in mind that a system of linear equations will consist of two equations using the same variables and the variables will represent the same thing for both equations, i.e., if you use X as a variable in the first equation and X represents a number of footballs then you need to use X in the second equation and it needs to represent number of footballs in the second equation.
