Answer:
<em>x = 0 </em>
<em>y = 2</em>
<em>z = -3</em>
Step-by-step explanation:
x-y-2z=4 (1)
-x+2y+z=1 (2)
-x+y-3z=11 (3)
(1) + (3) = x-y-2z + (-x)+y-3z = 4+11
= -5z = 15
-> z = -3
(1) + (2) = x - y - 2z + (-x) + 2y + z = 4+1
= y-z = 5
= y- (-3) = 5
-> y = 2
(1) = x-y-2z = 4
= x - 2 - 2 * (-3) = 4
-> x = 0
Answer:if im right you need to do 54 divided by 2= 27 so 27+27=54
Step-by-step explanation:
I believe it is c if i am not wrong
