Systems of three linear equations practice
Systems of three linear equations · 1–12
Solve the system. Write the answer as (x, y, z).
1.2x + y + z = 13x − y + z = 0x + 2y − z = 11
2.2x + y + z = 11x − y + z = 6x + 2y − z = 1
3.x + y − z = −2x − 2y + z = 53x + y + z = 12
4.x + 2y − z = 42x − y + z = 3x + y + z = 10
5.x + y − z = 4x − 2y + z = 33x + y + z = 22
6.x + y − z = 3x − 2y + z = 33x + y + z = 17
7.x + y − z = 0x − 2y + z = 13x + y + z = 6
8.x + y + z = 6x − y + 2z = 22x + y − z = 3
9.x + y + z = 11x − y + 2z = 42x + y − z = 8
10.x + y − z = 2x − 2y + z = 33x + y + z = 20
11.x + y − z = 2x − 2y + z = 13x + y + z = 16
12.x + y + z = 12x − y + 2z = 132x + y − z = 7
