HI,
The problem is:
x/800,000 = (x-1,000,000)/320,000
I can simplify to:
x = 800,000 ((x-1,000,000)/320,000)
x = 2.5 (x - 1,000,000)

Can someone please solve for X? My brain is so fried, I can't figure out what I'm doing.

x = 2.5(x - 1000000)
x = 2.5x - 2500000
2.5x - x = 2500000
1.5x = 2500000
x = 2500000 / 1.5 = 5000000 / 3 = 1666666 2/3

x/800,000 = (x-1,000,000)/320,000

Cross multiply
x * 320,000 = (x - 1,000,000) * 800,000

Simplify
320,000x = 800,000x - 800,000,000,000
480,000x = 800,000,000,000
x = 1,666,666 2/3

Multiply both sides by 320,000...

(x * 320,000) / 800,000 = x - 1,000,000

Subtract x from both sides.

[(x * 320,000) / 800,000] - x = -1,000,000

Simplify and find a common denominator.

(x * 2) / 5 - x = -1,000,000
(x * 2) / 5 - (x * 5 ) / 5 = -1,000,000

Combine like terms.

(2x - 5x) / 5 = -1,000,000
(-3x) = -1,000,000 * 5
x = 5,000,000 / 3

x(1 - 320,000/800,000) = 1,000,000

x = 1,000,000 / (1 - 2/5)
x= 1,000,000 * (5/3)

x/800,000 = (x -1,000,000) /320,000

multiply both sides by 1600,000

=> 2x = 5x -5,000,000

=> - 3x = -5,000,000

=> 3x = 5,000,000

x = 5,000,000 / 3

= 1, 666, 666 point 6666666666.....

Rounded to two Decimal places:

The answer is x = 1,666,666.67 (rounded to two decimal places. or by fraction,
x = 1,666,666 and 2 / 3 (to be exact)

_
1666666.6 or 1666666 2/3.

_ _
P.S. This is a repeater: , which means .6= .666666666666666666666666666666666666666666666666666666666666 and so on.

x=800,000*(x-1,000,000)/320,000
x= 2.5x-2,500,000
-1.5x = 2,500,000
x = -1,666,666.6666666666666666666666667

Is the "-" sign a subtraction sign or is the number negative?
