A. (3,2)

3(2x-y=4)
2x+3y=12

Than cross put the y’s

8x= 24

X= 3

Than substitute the x into one of the original equations

3•2 + 3y = 12
6+ 3y = 12
-6 -6

3y = 6
/3. /3

y= 2

Step-by-step explanation:

2x+3y=12

2x- y =4

-------------------------------------

subtraction. 4y=8

y=2

putting the value of y=2

2x-y=4

2x-2=4

2x=6

x=3

(3,2)

option A

To get an average, you must do the following steps.

step 1:add all the numbers together.
190258.50+152698.00+122753.00+220523.00+231951.00= 918183.5Step 2: divide the ANSWER you get by the amount of numbers there are:
(in this case, it will be 5, because you added 5 numbers together)
918183.5/5

your answer is: 183636.7
that is your average

hope this helps :D
