Solving linear systems with 3 variables (video)

Substitute z = 3 into equation (1). Substitute x = 4 and z = 3 into equation (2). Use the original equations to check the solution (the check is left to you). The solution is x = 4, y = –2, z = 3.

Solutions Using Elimination with Three Variables

Solve by using Cramer's rule $$ \begin{aligned} -x + \frac{2}{3}y - 2z & = 2 \\[2ex] 5x + 7y - 5z & = 6 \\[2ex] \frac{1}{4}x + y - \frac{1}{2}z & = 2 \end{aligned} $$ About Cramer's rule This calculator
