What is the solution to this system of linear equations? y-x=6 y+x=-10 (-2,-8) (-8,-2) (6,-10) (-10,6)

x=-8, y=-2. (-8, -2).

Step-by-step explanation:

y-x=6

y+x=-10

2y=-4

y=-4/2=-2

-2-x=6

x=-2-6=-8

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
