Question

efetue essa operação (2xy-5x+y)-(3-2xy+x+3y)

Answer 1

= (2xy - 5x + y) - (3 - 2xy + x + 3y)

= 2xy - 5x + y - 3 + 2xy - x - 3y

= 2xy + 2xy - 5x - x + y - 3y - 3

= 4xy - 6x - 2y - 3

Answer 2

2xy−5x+y−3+2xy−x−3y

(2xy+2xy)+(−5x−x)+(y−3y)−3

4xy−6x−2y−3

Answer 3

2xy−5x+y−3+2xy−x−3y

(2xy+2xy)+(−5x−x)+(y−3y)−3

4xy−6x−2y−3
