The following system has no solution.
x+y+z= 15
2x+z = 1
27-z=7
true or false
1 answer:
Answer:
False
Step-by-step explanation:
Let us start with the most obvious one:
27 - z = 7
-27 - 27
_________
-z = -20
z = 20 [Plug this back into the other two equations to get the y-coordinate and x-coordinate of 4½ and -9½]; 4½ = y; -9½ = x
So, the solution is [-9½, 4½, 20].
