- Solve the system using the equation elimination . Write your answer as an ordered pair (x, y, z).
x + y + z = 3
X – y=5
y - z = -7

x = 2

y = -3

z = 4

( 2 , -3, 4 )

Step-by-step explanation:

x + y + z = 3 i

x – y =5 ii

y - z = -7 iii

ii + iii

x - z = -2 iv

i + ii

2x + z = 8 --- v

iv + v

3x = 6

x = 2

x=2 substitute for v

z = 4

x =2 substitute for ii

y = -3
