Algebra 2: Solving Systems of Three Equations
Solve each system of three linear equations in three variables. Every system has a unique solution; give x, y and z as exact integers.
- 1.Solve the system: x + y + z = -12; 3x + y + 4z = -38; -4x - y + 2z = 6
- 2.Solve the system: x + 2y - 3z = -1; 3x + 2y - 4z = -6; 3x + y - 3z = -7
- 3.Solve the system: -3x + 3y + z = -3; -3x - y + 4z = -37; x - 3y + 2z = -21
- 4.Solve the system: -x + 2y - 3z = -11; -2x - y + z = 11; -x + y - 2z = -6
- 5.Solve the system: -3x - 2y - 3z = 9; 3x + y + 2z = -14; 2x - 3y - 3z = -27
- 6.Solve the system: -x - 4y - z = -21; -x - y - 2z = -1; 2x - 4y + 4z = -28
