Step-by-step explanation:

$6x -(2y - 2x + 6z) \\ \\ \\If \: \: \: you \: \: \: remove the \: \: \: bracket, \\ the \: \: \: sign \: \: will \: \: be \: \: changed. \\ \\ \\ 6x -(2y - 2x + 6z) \\ \\ \\ 6x - 2y + 2x - 6z\\ \\ On \: \: taking \: \: 2 \: \: as \: \: common. \\ 2( {3x - y + x - 3z}) \\ \\ 4x - y - 3z \: \: \\ solve \: \: the \: \: \: equation \\ \\ 4x -( 4 - 3)y - 3z \\ \\ 4x - 4y + 3y- 3z \\ \\ 4(x - y) + 3(x - y) \\ \\( x - y)(4 + 3)$
