Answer:
x = 6, y = -4
Step-by-step explanation:
x=-2y-2
4x+2y=16 .... divide by 2 both sides
2x + y = 8 ... subtitute x
2 ( -2y - 2) + y = 8
-4y - 4 + y = 8
- 3y = 8 + 4 = 12
y = -4
x = (-2 * -4) - 2 = 6
Its d. Each input only needs one output. It doesn’t matter if the output is the same. It searched this up on Google.
1/4 + 1/3 + 1/6 = 3/12 + 4/12 + 2/12 = 9/12 reduces to 3/4...leaving 1/4 for worker z.
answer is : 1/4 hrs was allocated to worker z
<span> Suppose the # of litres in the small container is 'x'.
This would make '2x' litres of water in the larger container.
After taking 8 litres from both containers, the following equation can be written:
(2x-8) = 3 (x-8)
Open the brackets:
2x-8 = 3x-24
Collect like terms:
x = 16
There were 16 litres in the smaller container</span>
5x+6=2(2x-3)
5x-4x+6=-6
X=-6-6
Answer:x=-12
