Simplifying
7x + -1[-5(x + -1y) + (3x + -2y) + -3(2x + -5y)] = 0
7x + -1[(x * -5 + -1y * -5) + (3x + -2y) + -3(2x + -5y)] = 0
7x + -1[(-5x + 5y) + (3x + -2y) + -3(2x + -5y)] = 0

Remove parenthesis around (3x + -2y)
7x + -1[-5x + 5y + 3x + -2y + -3(2x + -5y)] = 0
7x + -1[-5x + 5y + 3x + -2y + (2x * -3 + -5y * -3)] = 0
7x + -1[-5x + 5y + 3x + -2y + (-6x + 15y)] = 0

Reorder the terms:
7x + -1[-5x + 3x + -6x + 5y + -2y + 15y] = 0

Combine like terms: -5x + 3x = -2x
7x + -1[-2x + -6x + 5y + -2y + 15y] = 0

Combine like terms: -2x + -6x = -8x
7x + -1[-8x + 5y + -2y + 15y] = 0
