0.55x+0.45(2-x)=0.3(-1)

Solution for 0.55x+0.45(2-x)=0.3(-1) equation:

Simplifying
0.55x + 0.45(2 + -1x) = 0.3(-1)
0.55x + (2 * 0.45 + -1x * 0.45) = 0.3(-1)
0.55x + (0.9 + -0.45x) = 0.3(-1)

Reorder the terms:
0.9 + 0.55x + -0.45x = 0.3(-1)

Combine like terms: 0.55x + -0.45x = 0.1x
0.9 + 0.1x = 0.3(-1)

Multiply 0.3 * -1
0.9 + 0.1x = -0.3

Solving
0.9 + 0.1x = -0.3

Solving for variable 'x'.

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

Add '-0.9' to each side of the equation.
0.9 + -0.9 + 0.1x = -0.3 + -0.9

Combine like terms: 0.9 + -0.9 = 0.0
0.0 + 0.1x = -0.3 + -0.9
0.1x = -0.3 + -0.9

Combine like terms: -0.3 + -0.9 = -1.2
0.1x = -1.2

Divide each side by '0.1'.
x = -12

Simplifying
x = -12
