Answer:
i think is angle 7 n angle 15
Step-by-step explanation:
Times 2nd equation by 2
add to first equation
3x+6y=6
<u>4x-6y=8 +</u>
7x+0y=14
7x=14
divide both sides by 7
x=2
sub back
2x-3y=4
2(2)-3y=4
4-3y=4
minus 4 both sideds
-3y=0
y=0
(x,y)
(2,0)
Answer: 
Step-by-step explanation:
Given the equation 
, you need find the value of the variable x.
Then, you have to solve for x:
Add 
to both sides of the equation.
Divide by -8 to both sides of the equation.
Once you do this proccedure, you will get the value of the variable x.
Then:
Median = 14
Explanation:
Median: is when you find middle number in this set from low > high
12, 13, 13, 14, 21, 22, 23
Mean = 16
Explanation:
Mean: add all numbers up then divide by how many numbers are there
13 + 14 + 12 + 23 + 22 + 21 / 7 = 16
