The answer is -4 + 2 + -0.25 + 0.5.
The answer to The solution is2x- 5y=-21
Answer: 2,3,8
Step-by-step explanation:
if,
x+y+z=13
2x+5y+6z=67
5x-y=7
Solve [x+y+z=13 2x+5y+6z=67] to find: -3x+z=2 and keep
|
x+y+z=13
5x-y=7
6x+z=20 and -3x+z=2
z=8
x=2
y=3
N/0.05 - 2 < -4.6
n/0.05 < -4.6 + 2
n/0.05 < --2.6
n < -0.13
