system of equation substitution method


System of Equation 

Free Math Education (Algebra Math) Students learn to solve systems of equations by substitution by first isolating a variable in one of the equations in the system, then substituting its value for the corresponding variable in the other equation. You can also learn to solve the equations by the method of their choice using the following rules: 
if one of the variables cancels out when the equations are added together, then use addition, and if a variable is already isolated in one of the equations, use substitution method.

We also Provide  the math algebra tutorials .
