Question:
Any equation involving two variables of one degree each is said to be a linear equation of two variables and when we consider a number of such equations it is called a System of Linear Equations in Two Variables.
Let ax+by=pax+by=p ...... (1)
be a linear (when the degree or the highest power of the variable is one) equation of two variables where a, b, and p are constants belonging to the set of real numbers again another linear equation of two variables be
cx+dy=qcx+dy=q ...... (2)
Where c, d, and q are constants of real numbers
When we represent equations (1) and (2) together it forms a system of linear equations in two variables.
In order to get a solution to a system of linear equation, it has to be remembered that if two linear equations are there, there has to be two variables involved in the equations.
