Question

-(3x-5y+4x)-(4-x+7y+11-4x)-(12-3y+3x)=

Answer 1

Respuesta:

−(3x−5y+4x)−(4−x+7y+11−4x)−(12−3y+3x)

−((3x+4x)−5y)−(4−x+7y+11−4x)−(12−3y+3x)

−(7x−5y)−(4−x+7y+11−4x)−(12−3y+3x)

−(7x−5y)−((4+11)+(−x−4x)+7y)−(12−3y+3x)

−(7x−5y)−(15−5x+7y)−(12−3y+3x)

−7x+5y−15+5x−7y−12+3y−3x

(−7x+5x−3x)+(5y−7y+3y)+(−15−12)

−5x+y−27
