Answer:
A. 2x - (4x + 3) = 12
Step-by-step explanation:
A. 2x - (4x + 3) = 12
B. -4(4y+)+y=3
C. 2 (4x+3) - y
D. -4x+4 x-3=3
Given equation:
-4x+y = 3. (1)
2x - y = 12. (2)
From (1)
y = 3 + 4x
Substitute y = 3 + 4x into (2)
2x - y = 12 (2)
2x - (3 + 4x) = 12
Or
2x - (4x + 3) = 12
2x - 4x - 3 = 12
- 2x = 12 + 3
- 2x = 15
x = 15/-2
x = -7.5
Substitute x = -7.5 into (1)
-4x+y = 3 (1)
-4(-7.5) + y = 3
30 + y = 3
y = 3 - 30
y = -27
42-13=29
29 times 2= 58

Answer:
(-1,4)
Step-by-step explanation:
basically take x and subtract it from the other x and in the same order subtract the y's
Answer:
Averages don't tell the whole story..
Step-by-step explanation:
Averages do not tell the full story of an event. Since there are not one, not two, but three types of averages, namely; Mean, Mode, and Median, this means there is a 100/3 = 33.3 percent chance of someone guessing which of the averages was used.
This can be misleading.
