4 LITTLE DOG Solve the following systems of equations: 2x + 4y + 3z = 14 y + 3z = 11 z = 4

5 ANSWER Solve the following systems of equations: 2x + 4y + 3z = 14 y + 3z = 11 z = 4(3, -1, 4)

6 BIG DOG Solve the following systems of equations: 2x + 3y + 2z = 18 -4y + y – z = 5 2z = -10

7 ANSWER Solve the following systems of equations: 2x + 3y + 2z = 18 -4y + y – z = 5 2z = -10(2, 8, -5)
