(10 * 0.25 + x * 0.25) + -0.03(x + -20) = -5.7
(2.5 + 0.25x) + -0.03(x + -20) = -5.7

Reorder the terms:
2.5 + 0.25x + -0.03(-20 + x) = -5.7
2.5 + 0.25x + (-20 * -0.03 + x * -0.03) = -5.7
2.5 + 0.25x + (0.6 + -0.03x) = -5.7

Reorder the terms:
2.5 + 0.6 + 0.25x + -0.03x = -5.7

Combine like terms: 2.5 + 0.6 = 3.1
3.1 + 0.25x + -0.03x = -5.7

Combine like terms: 0.25x + -0.03x = 0.22x
3.1 + 0.22x = -5.7

Solving
3.1 + 0.22x = -5.7

Solving for variable 'x'.

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

Add '-3.1' to each side of the equation.
3.1 + -3.1 + 0.22x = -5.7 + -3.1

Combine like terms: 3.1 + -3.1 = 0.0
0.0 + 0.22x = -5.7 + -3.1
0.22x = -5.7 + -3.1

Combine like terms: -5.7 + -3.1 = -8.8
0.22x = -8.8

Divide each side by '0.22'.
x = -40

Simplifying
x = -40
