Explanation:

$y - [ - x - (y + 15)] \\ = ( - 9) - [ - (18)- (( - 9) + 15)] \\ = ( - 9) - [ - (18)- ( 6)] \\ = ( - 9) - [ - 24] \\ = - 9 + 24 = \boxed{15} \\ \\ - 6(x - 2) - 5(x + 7) \\ = - 6x + 12 - 5x - 35 \\\boxed{ = - 11x - 23 }\\ \\ (3)/(4)( 4x + (4)/(3) ) = 4x \\ 3x + 1 = 4x \\ 4x - 3x = 1 \\ \boxed{ x = 1}$
