Help me @dude.

darkknight:

k

darkknight:

what math are you in

WildWest05:

{y=x+2 {y=-3/5x-6

WildWest05:

Algebra 1. I'm a freshman in high school with 56 missing assignments...

darkknight:

hey dude, can you help me with my problem while I help him

darkknight:

same, i'm a freshmen in high school in pre-calc. but I have 0 missing assignments

WildWest05:

I am actually excited to get into geometry cuz I was godly at that back in grade school

darkknight:

nice

darkknight:

whats the problem

darkknight:

what do you have to do?

WildWest05:

Solve each system of equations by graphing. Show all work on the attached paper. Use your solutions to navigate through the maze.

WildWest05:

I basically have to graph it and find my way through the maze.

darkknight:

so can you use a graphing calculator?

WildWest05:

I can but I don't have one...

WildWest05:

But I have to show my work too sooo....

WildWest05:

She's really strict on showing work.

darkknight:

ok

darkknight:

there is a way to do it without a graphing calculator, and easy calculations

WildWest05:

Sorry my internet cut out for a sec

WildWest05:

Gotta love hotel wifi am I right?

darkknight:

to solve systems of equations you can set them equal to each other and solve for the x value. (which is where they intersect) then plug it back in and find the y-value) In your case y=x+2 and y=-3/5x-6. Set them equal to each other so x+2 = -3/5x-6, isolate x by subtracting 2 from both sides. which results in x= -3/5x-8. Then add 3/5x to both sides so it becomes 8/5x=-8 then multiply by 5 on both sides so 8x=-40. Then divide by 8 to get x=-5. plug it back in any of the equations and find the y-value

WildWest05:

WHAT THE FREAK JUST HAPPENED TO MY BRAIN?!

WildWest05:

MY BRAIN WENT FROM "You got this bro" TO "HELP ME. GOD PLEASE HELP ME"

WildWest05:

That made 0 sense to me. I missed like 30-50 days this semester and my brain just exploded because I did not understand a word there

darkknight:

sorry man, its been a while since I've been in algebra 1

WildWest05:

I see that

darkknight:

try rereading it again and see if that helps

WildWest05:

I read it like 5 times. That's what took me so long to reply.

darkknight:

so pretty much y=x+2 and y=-3/5x-6 x+2=-3/5x-6 x=-3/5x-8 x+3/5x=-8 8/5x=-8 8x=-40 x=-5

WildWest05:

I still don't understand.

WildWest05:

I am no help am I? lol

darkknight:

I'll explain what I did in all my steps

WildWest05:

Okay that would probably help me a lot

darkknight:

so pretty much y=x+2 and y=-3/5x-6 x+2=-3/5x-6 x=-3/5x-8 x+3/5x=-8 8/5x=-8 8x=-40 x=-5 step 1, both equations step 2 set them equal to each other step 3 subtract 2 fromboth sides, so we can get x by itself step 4 add 3/5x to both sides, now there is no x on the right side and x+3/5x on the left step 5 add the x terms step 6 multiply both sides by 5, helps get x by itself step 7 divide both sides by 8 to get x by itself which is -5

darkknight:

I can't give a better explanation, try to talk to your teachers and see if you can be caught up

WildWest05:

I am more confused than I was before the explanation...

WildWest05:

My teacher basically hates me because of how far behind I am...

darkknight:

sorry man, cant help much then, try asking someone else

WildWest05:

If @dude was online I'd ask him but he's not :(
