Solution for (2.5)-x(x+1)=x(2-x) equation:


Simplifying
(2.5) + -1x(x + 1) = x(2 + -1x)
2.5 + -1x(x + 1) = x(2 + -1x)

Reorder the terms:
2.5 + -1x(1 + x) = x(2 + -1x)
2.5 + (1 * -1x + x * -1x) = x(2 + -1x)
2.5 + (-1x + -1x2) = x(2 + -1x)
2.5 + -1x + -1x2 = (2 * x + -1x * x)
2.5 + -1x + -1x2 = (2x + -1x2)

Add 'x2' to each side of the equation.
2.5 + -1x + -1x2 + x2 = 2x + -1x2 + x2

Combine like terms: -1x2 + x2 = 0
2.5 + -1x + 0 = 2x + -1x2 + x2
2.5 + -1x = 2x + -1x2 + x2

Combine like terms: -1x2 + x2 = 0
2.5 + -1x = 2x + 0
2.5 + -1x = 2x

Solving
2.5 + -1x = 2x

Solving for variable 'x'.

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

Add '-2x' to each side of the equation.
2.5 + -1x + -2x = 2x + -2x

Combine like terms: -1x + -2x = -3x
2.5 + -3x = 2x + -2x

Combine like terms: 2x + -2x = 0
2.5 + -3x = 0

Add '-2.5' to each side of the equation.
2.5 + -2.5 + -3x = 0 + -2.5

Combine like terms: 2.5 + -2.5 = 0.0
0.0 + -3x = 0 + -2.5
-3x = 0 + -2.5

Combine like terms: 0 + -2.5 = -2.5
-3x = -2.5

Divide each side by '-3'.
x = 0.8333333333

Simplifying
x = 0.8333333333
