■ What are Linear Equations in two variable ?

>> An equation in form of $\rm ax + by + c =0,$ where a, b, & c are real number.

>> It provide us two unknown quantites when solved.

>> When It is represented on a cartesian plan, it does intersect at point, which is its solution too.

• Substituition method :-

▪This is a way to solve linear equations of two variable.

▪In this, we transform any one(among two) of the equations as Equation in one variable.

▪Then, We put the new obtained equation in other remaining Equation.

▪On further solving, we get the value of one variable.

▪Thus, On putting the obtained value of one variable, we can get other variable's value too.
