PreCalcP6 6.1 Multivariable Linear Systems and Row Operations PreCalcP6 6.1 Multivariable Linear Systems and Row Operations Solve this system of equations. x + 3y + 2z = 5 3x + y – 2z = 7 2x + 2y + 3z = 3 PreCalcP6 6.1 Multivariable Linear Systems and Row Operations What is a matrix? Important vocabulary: Row Column Element Solve this system of equations. Let's use a matrix! (Actually, an augmented matrix) x + 3y + 2z = 5 3x + y – 2z = 7 2x + 2y + 3z = 3 PreCalcP6 6.1 Multivariable Linear Systems and Row Operations Solve this system of equations. Let's use a matrix!
