Need math help

Ballery1:

Find the equilibrium and price for each pair of supply and demand equations. (x is measured in units of a thousand, and *p* in dollars) \[P^2 +3P -x = 16 ; x + 3P - 24 = 0 \]

Ballery1:

Those are two equations. One represents the supply equation and the other represents the demand equation.

Ballery1:

How do i find the equilibrium of number of units and price?

mhchen:

Wherever supply = demand. Can you graph them? |dw:1568161211304:dw|

mhchen:

Or just solve them like a system of equation

Ballery1:

I’m trying to solve this as a system of equations but it’s not as easy... i’m Not getting the right answer mate

Ballery1:

I’m working on a different question atm, gimme like 5-10 minutes :)

mhchen:

x = P^2 + 3P - 16 Substitute: (P^2 + 3P - 16) + 3P - 24 = 0

Ballery1:

Wait, what variable am i solving for here? I’m doing the same thing but i’m Getting x = 12 p = 4... I’m getting the opposite answer...i’m Getting x = 4

Ballery1:

Sorry, let me correct myself, the answer from the textbook is x = 12 and p = 4...i’m Getting x = 4

Ballery1:

Am i solving for the wrong variable here?

Ballery1:

Gimme 10 minutes now... i need to finish this question... it’s a different question

Ballery1:

Yup, i figured it out now... I’m getting the right answer for both demand and prince equilibriums...jajajjaajaja thanks... i just needed a lil push

Ballery1:

I’ll post the answer in about 10 minutes or so.. I’m working on log questions atm thanks tho :)

Ballery1:

Jesus this is a long question... i’ll Post the pictures.

Ballery1:

Can yall see the ting?

Seems like the right approach, I'm not checking in depth if there's a computational error. If you did the math correctly, I'd say it's fine. It's always a good habit of showing all your work and keep doing it! But dude, this shouldn't take a page front and back and take that long, js. Maybe practice up a bit more, doing it for the first time can take a lot of time and space.

Ferredoxin4:

This is from Algebra 1 right?

mhchen:

I don't have time to check your work, I can only offer help when you're stuck. Sorry bud, but my own math is killing me as well.

Ballery1:

I’m making notes to make sure when i leave math to study something else... i’ll Have everything laid out for me in baby steps... so i can just see and know the method to do different questions..

Ballery1:

So when i come back to it... i’ll Have the steps to guide me to relearn everything fast.

Ballery1:

I could def synthesize my solutions but i need to show every fewking step so i don’t have to relearn the itsibitsis of maths all over again

Ballery1:

I’ll chall know when I’m stuck on the next question. Love you all :* :)
