Question

Please Show Me Step By Step :)
*** Solve for X ****
1.) ax + 2xy = 14
2.) x/a = y/b
3.) 2m - nx = x+4

*** Solve For H ***
4.) this one i had to make an attachment

Answer 1

Are these separate equations..?

Answer 2

Here is # 4please help! :)

Answer 3

yeah

Answer 4

Take x common for the first...

Answer 5

okay and I got
m = 2, n = -1
is that correct

Answer 6

I'm pretty sure you should not have gotten an answer with the information you have.
They just want you to manipulate the equations to get nice f(x) functions.
1) ax+2xy=14
\[2xy=14-ax\]
\[y=\frac{ 14-ax }{ 2x } = \frac{ 7 }{ x }-\frac{ a }{ 2}\]
2)\[\frac{ xb }{ a }=y\]

Answer 7

oh okay so are these the answers?

Answer 8

They are good answers, I'm not sure if they're the answers you're looking for. I studied in french before university, so I'm not used to the precalculus (if that's the course) vocabulary in english

Answer 9

what's certain is that you cannot get discrete values for x, y, m, n or v with only what you've shown us

Answer 10

the course is Variables and Expressions

Answer 11

they answers would either be the ones I gave you, or
1)\[x=\frac{ 14 }{ 2y+a }\]
2)\[x=\frac{ ay }{ b }\]

if this makes sense to you, you should be able to do the other 2

Answer 12

okay and it does

Answer 13

good!
