Answer:
X = -y -3
X= -2y + 3 (if correct, please mark brainliest. :))
Step-by-step explanation:
The three students whose individual number of shirt owned sums up to 20 are <em>Will, Mandy and Cindy</em>.
<u>Given the information about the number of t-shirts owned by 4 students</u> :
- Will 4
- Mandy 7
- Greg 12
- Cindy9
<u>To obtain the which three students have shirts which sums up to 20</u> ;
- We could sum the number of t-shirts owned by any of the three students and see if it gives a value of 20.
- From the data, the 3 students who have the least number of t - shirts have a total of 20 t - shirts
<em>Will + Mandy + Cindy</em>
4 + 7 + 9 = 20 students
Therefore, the three students whosw shirts sums up to 20
are <em>Will, Mandy and Cindy</em>.

I don't think you can give medals on this site, but ok
a way to simplify it is to solve for y
x+2y=8
minus x both sides
2y=8-x
divide both sides by 2
y=4-x/2
(x,y)
just sub points in (sub x values for x and see if you get the coresponding y value)
example
point (8,0)
x=8 and the resulting y should eual 0
y=4-x/2
y=4-8/2
y=4-4
y=0
yes
A. (8,0) works, (6,1) works, (4,2) works
B. (2,4) doesn't work, so this option is wrong
C. (0,8) doesn't work, so this option is wrong
D. (0,8) still , doesn't work, so this option is wrong
answer is A
