WebIn mathematics, the system of linear equations is the set of two or more linear equations involving the same variables. Here, linear equations can be defined as the equations of the first order, i.e., the highest power of the variable is 1. Linear equations can have one variable, two variables, or three variables. WebMay 3, 2024 · Firstly you need atleast 3 DISTINCT equations if you need to solve for 3 variables. In your question, not only did you provide only 2 equations, both of them are identical, divide by 2 and check. So it's just a single equation in 3 variables. Unless there are certain constraints you have infinite solutions.
