Linear Equations in One Variable
An equation of one variable and of first order (i.e., its highest power is one) is called a Linear equation. Such an equation has only one solution. A solution is also called the 'root' of the given equation.An equation of one variabl..

Really liked thier styling of tutoring. Very helpful. they went step by step and had me work out the answer- Adad
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
Tutor Vista tutor helped me understand and gave me some practices and showed me how to do them.
