the best way for solving for both variables is to use the substitution method, which involves solving for one variable as far as possible, then plugging it back in to the other equation. Knowing how to solve a system of equations with two variables...
Cite this lesson A system of linear equations in two variables is an important concept that is used in many math disciplines. Review a detailed explanation of these systems and explore how to solve them using the substitution method. System...
The substitution method of solving a linear system is generally used to solve a two-variable linear system. A two-variable linear system is written as under- $$\begin{align} a_1x + b_1y & = c_1 \\[0.2 cm] a_2x + b_2y & = c_2 \\[0.2 cm] \end{align}\\ $$ ...
