1000=x+(x*.8)+(x*.3)

Solution for 1000=x+(x*.8)+(x*.3) equation:

Simplifying
1000 = x + (x * 0.8) + (x * 0.3)

Reorder the terms for easier multiplication:
1000 = x + (0.8x) + (x * 0.3)

Reorder the terms for easier multiplication:
1000 = x + (0.8x) + (0.3x)

Combine like terms: x + (0.8x) = 1.8x
1000 = 1.8x + (0.3x)

Combine like terms: 1.8x + (0.3x) = 2.1x
1000 = 2.1x

Solving
1000 = 2.1x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2.1x' to each side of the equation.
1000 + -2.1x = 2.1x + -2.1x

Combine like terms: 2.1x + -2.1x = 0.0
1000 + -2.1x = 0.0

Add '-1000' to each side of the equation.
1000 + -1000 + -2.1x = 0.0 + -1000

Combine like terms: 1000 + -1000 = 0
0 + -2.1x = 0.0 + -1000
-2.1x = 0.0 + -1000

Combine like terms: 0.0 + -1000 = -1000
-2.1x = -1000

Divide each side by '-2.1'.
x = 476.1904762

Simplifying
x = 476.1904762
