Elimination is where you aline two equations with the varibles in the same place and the second equation substracts the first equation. Important to know that in the second equation all varibles and constant or y - intercepts are negative. Now with this just start with the first two equations, 5x + 2y -3z = 10 and 2x - 2y + 4z = 6.

5x + 2y - 3z = 10

- 2x + 2y - 4z = -6

3x + 4y - 7z = 4

Do the same thing with the last equation.

3x + 4y - 7z = 4

-x + y - 2z = -3

2x + 5y -9z = 1

Please tell me if I got it wrong, but from what I concluded there's no solution.

A box contains marbles of five different colors: red, green, blue, yellow, and purple. there is an equal number of each color. a

P(red) = 1/5     [that says "probability of getting red is one fifth"
P(green) = 1/5
P(blue) = 1/5
P(yellow) = 1/5
P(purple) = 1/5

The reason the fractions are all the same is that there are equal numbers of each color.  For example, if there were 7 marbles of each color, there would be a total of 35 marbles.

P(red) = 7/35 = 1/5
Similar for the other colors.

List 2/3 , 7/12 , and 3/4 from greatest to least thanks .
nikklg [1K]
For this question you should know that:
2/3 = 8/12 
and 
3/4 = 9/12 
so now you can say:
7/12 < 8/12 < 9/12 
so: 
7/12 < 2/3 < 3/4 :)))
i hope this is helpful
have a nice day
