Solving systems of three equations with substitution worksheet answers with work

Equation 1) x – 6y – 2z = -8. Equation 2) -x + 5y + 3z = 2. Equation 3) 3x - 2y – 4z = 18 . Steps in order to solve systems of linear equations through substitution: Solve one of the equations for one of its variables. From the three variables, there is no incorrect choice so choose to solve for any variable. ü i.e.: x= 6y +2z -8.
