0.25x+0.15(2-x)=0.1(-1)

Solution for 0.25x+0.15(2-x)=0.1(-1) equation:

Simplifying
0.25x + 0.15(2 + -1x) = 0.1(-1)
0.25x + (2 * 0.15 + -1x * 0.15) = 0.1(-1)
0.25x + (0.3 + -0.15x) = 0.1(-1)

Reorder the terms:
0.3 + 0.25x + -0.15x = 0.1(-1)

Combine like terms: 0.25x + -0.15x = 0.1x
0.3 + 0.1x = 0.1(-1)

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

Solving
0.3 + 0.1x = -0.1

Solving for variable 'x'.

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

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

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

Combine like terms: -0.1 + -0.3 = -0.4
0.1x = -0.4

Divide each side by '0.1'.
x = -4

Simplifying
x = -4
