👉Learn how to solve a system of equations by substitution. To solve a system of equations means to obtain a common values of the variables that makes the each of the equation in the system true. To solve a system of equations by substitution, we solve for one of the variables in one of the equations and then substitute for the variable in the other equation and then solve for the other variable. Next we plug in the obtained value of the other variable into the equation for the initial variable we solved for to obtain the value of the variable.
The value of the two variables obtained is the solution to the system of equations.
