Answer:
a) - 11x - 94y / 12 b) x -4 / 5- 3x c) 12x - 11 /10y
Step-by-step explanation:
a) 2x - 6y / 4 - 4y - x/ 12 - 4x - 20y /3
6x - 18y / 12 - 4y - x / 12 - 16x - 80y / 12
= 5x - 14y / 12 - 16x - 80y / 12
- 11x - 94y / 12
b) x /5 - 4/ 3x = x -4 / 5- 3x
c) 2x -3/ 5y - 5- 2x / 10y + x/y
4x - 6 /10y - 5-2x/ 10y + 10x / 10y
2x - 11 / 10 + 10x / 10y
= 12x - 11 /10y
Answer:
Yes, Beyonce will get the same solution.
Step-by-step explanation:
The given system is
2x - 3y = - 2
and
4x + y = 24
If she multiplies the first equation by -2 , she gets,
-4x+6y=4
4x + y = 24
Adding the two equations gives
7y=28
This means y=4
When we put y=4 into the bottom equation we get:
4x+4=24
4x=20
x=5
Therefore Beyonce will still get x=5, and y=4 as solution.

Answer:
Step-by-step explanation:
the whole bag is made of 5 orange +4blue+3 green= 12 marbles
