Step-by-step explanation:

xét tam giác abc có:

bd/ba=be/bc

<=>x+2/2x+2=3/5

<=>(x+2)5=3(2x+2)

<=>5x+10=6x+12

<=>x=-2

Answer:

x = 4

Step-by-step explanation:

Given a line parallel to the side of a triangle and it intersects the other 2 sides then it divides those sides proportionally , that is

[tex]\frac{BD}{DA}[/tex] = [tex]\frac{BE}{EC}[/tex] , substitute values

[tex]\frac{x+2}{x}[/tex] = [tex]\frac{3}{2}[/tex] ( cross- multiply )

3x = 2(x + 2)

3x = 2x + 4 ( subtract 2x from both sides )

x = 4
