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
7(2x + 3) + 2(2x + 4)
Distribute/multiply 7 into (2x + 3), and distribute 2 into (2x + 4)
(2x(7) + 3(7)) + (2x(2) + 4(2))
14x + 21 + 4x + 8 Combine like terms
18x + 29
