6x – 5y + 3z = 26
4x + 8y – 11z = 7
5x – 6y + 2z = 12
Given the equations above, x + y + z = ?	Choose the correct choice:
A) 11
B) 12
C) 13
D) 14
E) 15
(6x – 5y + 3z) - (5x – 6y + 2z ) = 26-12   or, x+y+z = 14   Option 14 is the ans
<result>D</result>
6x – 5y + 3z = 26
4x + 8y – 11z = 7
5x – 6y + 2z = 12
Given the equations above, x + y + z = ?
