Solve the following (x-2)+4=3x-2

Step-by-step explanation:

Hey there!

To find x we need to finagle it out by combining like terms and using the communicative property.

x - 2 + 4 = 3x - 2

Simplify

x + 2 = 3x - 2

-x to both sides

2 = 2x - 2

+2 to both sides

4 = 2x

Divide both sides by 2

x = 2

Hope this helps :)

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.
