a. (5,2)
b. (7,2)
c. (11,1)

Answer 1

can you solve for y?

Answer 2

I am completely clueless :(

Answer 3

ok, can you tell me where it starts?

Answer 4

like your confusion

Answer 5

wouldnt you start out like this?
(x+3) y = 14
xy + 3y = 14

Answer 6

you could, but actually, you don't even have to make it that hard. It's one step(think of how you'd solve for b here: (4+9)b=10)

Answer 7

Oh i kinda get it! the answer would be c right?
you can plug in the numbers and (11+3)1 = 14 ;)
i think thats it anyways

Answer 8

huh, wait no thta's not what I was getting at, but that is a way... not a good way because then you don't get the concept, though it works

Answer 9

if you can solve for x or y, you get a form that makes it really to check as opposed to slighty more difficult(YOUR APPROACH)

Answer 10

OOPS SORRY FOR THE CAPS!

Answer 11

oops again lol

Answer 12

Thank You so much! :) and its okay xD

Answer 13

ok, so real quick, how i would do it: solve for y real quick just divide both sides by (x+3)
\[(x+3)y=14\]
\[y=\frac{14}{x+3}\]
then do your plug and chugs
