Answer 2

Step-by-step explanation:

Solve for X, Y, and Z in the following systems of three equations using either substition or elimination methods:

a. X + 2Y + Z = 6

X + Y = 4

3X + Y + Z = 8

b. 10X + Y + Z = 12

8X + 2Y +Z = 11

20X - 10Y - 2Z = 8

c. 22X + 5Y + 7Z = 12

10X + 3Y + 2Z = 5

9X + 2Y + 12Z = 14
