then factor it out. If nobody's done it by the time i'm done eating this sushi, I will.
this is wrong, but I'll try to figure this out anyway to the best of my ability. But it's been like 2 years since I've done anything like this.

(solve for x)

8x+22y-40,000 = 0.

8x+22y=40,000
8x = -22y+40,000

goddamnit i lost my fucking graphing calculator. windows calculator -ev.

*x= -22/8y + 5,000*

(solve for Y)

8x+22y=40,000

22y = -8x +40,000

*y = -8/22x + 1818.18*


(plug x value back into original equation)

8 (-22/8y + 5,000) + 22y = 40,000
-22y + 40,000 + 22y = 40,000

40,000 = 40,000

no shit asshole

ALRIGHT LETS TRY PLUGGING Y INTO THE ORIGINAL EQUATION. GRAPHING CALCULATOR = MUCH BETTER.


y = -8/22x + 1818.18

8x + 22 (-8/22x + 1818.18) = 40,000

8x + -8x + 40,000 = 40,000
40,000 = 40,000

omg so fucking rigg3d

ALRIGHT LETS TRY PLUGGING THE X FORUMLA INTO THE Y FORUMLA, BOTH OF WHICH I SOLVED FOR



x= -22/8y + 5,000
y = -8/22x + 1818.18

x = -22/8(-8/22x + 1818.18) + 5000
x = x - 5000 + 5000

x=x (as an aside, this is always, 100% true, so you can't say I'm wrong.)

jesus christ, this was so easy for me back in the day....


anyway I'm sure I made an error somewhere along the way and I'm gonna come here tomorrow and correct it. Seriously. Too tired now.
