Question

Simplify: 3x-[4x - 3x - 5y-3{2x - (3x - 2x -3y)}]​

Answer 1

ANSWER:

$5x + 11y$

EXPLANATION:

$3x - (4x - 3x - 5y - 3(2x - (3x - 2x - 3y)))$

$= 3x - (4x - 3x - 5y - 3(2x - (x - 3y)))$

$= 3x - (4x - 3x - 5y - 3(2x - x + 3y))$

$= 3x - (4x - 3x - 5y - 3(x + 3y))$

$= 3x - (4x - 3x - 5y - 3x - 6y)$

$= 3x - ( - 2x - 11y)$

$= 3x + 2x + 11y$

$= 5x + 11y$
