Answer 1

Tách ra đi bn 

Answer 2

1: \(\Leftrightarrow B+2x^2y^3=xy+x^2y^3\)

=>B=xy-x^2y^3

2: \(\Leftrightarrow B-x^3y=x^2-x^3y\)

=>B=x^2

3: =>-B-3y=-3y-2x^3y^6

=>-B=-2x^3y^6

=>B=2x^3y^6

4: =>\(B-xy^4=2y^4-xy^4\)

=>B=2y^4

5: =>\(B-\dfrac{5}{3}y^2=\dfrac{2}{3}x^2-\dfrac{5}{3}y^2\)

=>B=2/3x^2

6: =>\(B-\dfrac{5}{12}x^3y^3=\dfrac{4}{3}x^2y^2-\dfrac{5}{12}x^3y^3\)

=>B=4/3x^2y^2
