Answer:

x = - [tex]\frac{7}{10}[/tex]

Step-by-step explanation:

A theorem states that (using letters from in this problem) that:

AB * BE = DC * CE

Applying that you can find that:

11 ( x + 1 ) = 1 ( x + 4 )

11 x + 11 = x + 4

11 x + 11 - x = x + 4 - x

10 x + 11 = 4

10 x + 11 - 11 = 4 - 11

10 x = -7

10 x / 10 = -7 / 10

x = - [tex]\frac{7}{10}[/tex]
