**How to Solve a system of linear equations via substitution**

The substitution method has these basic steps: Solve eq.1 for z. Substitute the whole right-hand side of the equation (the one you just wrote) in place of "z" in eq.2. You should use parentheses around the substituted expression to keep everything orderly. Solve the equation you wrote in step 2 for y.... The method of substitution is based on the principle of equivalency. What this means is that the definition of any variable in a system will be consistent throughout the system. In other words the [math]x[/math] in one equation will be equivalent to [math]x[/math] in any â€¦

2018-11-09Â Â· The substitution method works only with two equations in two unknowns (or three equations in three unknowns, etc.). Because Equation 1 contains three unknowns, you have two equations in three unknowns, and the substitution method will not work....2017-04-08Â Â· An old video where Sal introduces the substitution method for systems of linear equations.
