SOLUTION: Solve for X, Y, and Z in the following systems of three equations using either substition or elimination methods: a. X 2Y Z = 22 X Y = 15 3X Y Z = 37 b. 1

Question 270301: Solve for X, Y, and Z in the following systems of three equations using either substition or elimination methods:
a. X 2Y Z = 22
X Y = 15
3X Y Z = 37
b. 10X Y Z = 603
8X 2Y Z = 603
20X - 10Y - 2Z = -6
c. 22X 5Y 7Z = 12
10X 3Y 2Z = 5
9X 2Y 12Z = 14
