10[x + 3] + -1[-9x + -4] = x + -5 + 3

Reorder the terms:
10[3 + x] + -1[-9x + -4] = x + -5 + 3
[3 * 10 + x * 10] + -1[-9x + -4] = x + -5 + 3
[30 + 10x] + -1[-9x + -4] = x + -5 + 3

Reorder the terms:
30 + 10x + -1[-4 + -9x] = x + -5 + 3
30 + 10x + [-4 * -1 + -9x * -1] = x + -5 + 3
30 + 10x + [4 + 9x] = x + -5 + 3

Reorder the terms:
30 + 4 + 10x + 9x = x + -5 + 3

Combine like terms: 30 + 4 = 34
34 + 10x + 9x = x + -5 + 3

Combine like terms: 10x + 9x = 19x
34 + 19x = x + -5 + 3

Reorder the terms:
34 + 19x = -5 + 3 + x

Combine like terms: -5 + 3 = -2
34 + 19x = -2 + x

Solving
34 + 19x = -2 + x

Solving for variable 'x'.

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

Add '-1x' to each side of the equation.
34 + 19x + -1x = -2 + x + -1x

Combine like terms: 19x + -1x = 18x
34 + 18x = -2 + x + -1x

Combine like terms: x + -1x = 0
34 + 18x = -2 + 0
34 + 18x = -2

Add '-34' to each side of the equation.
34 + -34 + 18x = -2 + -34

Combine like terms: 34 + -34 = 0
0 + 18x = -2 + -34
18x = -2 + -34

Combine like terms: -2 + -34 = -36
18x = -36

Divide each side by '18'.
x = -2

Simplifying
x = -2
