How many solutions are there? 3x-7y=-14 -3x+6y

Many solutions

Step-by-step explanation:

Let's solve for x.

3x−7y=−14−3x+6y

Step 1: Add 3x to both sides.

3x−7y+3x=−3x+6y−14+3x

6x−7y=6y−14

Step 2: Add 7y to both sides.

6x−7y+7y=6y−14+7y

6x=13y−14

Step 3: Divide both sides by 6.

6x

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.
