Question

~~~~~~~~~~~~~FAN AND MEDAL~~~~~~~~~~~~~~
For the following system of equations, write your own real world scenario that describes what is happening. Use complete sentences and correct grammar in your scenario.

Part 2:
Solve the system and explain what the results mean according to your scenario.

2x + y = 10
3x + 4y = 25

Answer 1

you go to a (cheap) bar
2 shots and a beer cost $10
3 shots and 4 beers cost $25

how much is a beer, and how much is a shot?

Answer 2

if your teacher will not appreciate beers and shots, turn them in to hot dogs and sodas

Answer 3

lmaoo Okay but i dont know how to put this all together

Answer 4

you mean how do you solve it?

Answer 5

Oh nevermind This is pretty easy can you just come back when I'm finished so you can tell me if It looks right? :D

Answer 6

\[2x + y = 10 \\
3x + 4y = 25\]
first equation is the same as \(y=-2x+10\) so you can solve
\[3x+4(-2x+10)=25\] for \(x\) then solve for \(y\)

Answer 7

Can you teach me how to solve for x , and y please

Answer 8

\[3x+4(-2x+10)=25\] multiply out using the distributive law
\[3x-8x+40=25\] collect like terms\[-5x+40=25\] subtract \(40\)
\[-5x=-15\] divide by \(-5\)
\[x=3\]

Answer 9

Ok thank you and what about the y

Answer 10

\[2x+y=10\\
2\times 3+y=10\]is a start

Answer 11

Lol then its 4 eh
