E is the middle of [AC]

so AE = 1/2 x AC

then

4x = 1/2 * (6x + 5)

4x = 3x + 5/2

x = 5/2

x = 2,5

Answer:


x=\frac52

Explanation:

In a parallelogram, the diagonals bisect each other. This means that the diagonals are divided into 2 equal parts by the other diagonal.

Therefore,


\implies AE =\frac12 AC


\implies 4x=\frac12(6x+5)

To solve:

multiply both sides by 2:


\implies 8x=6x+5

subtract 6x from both sides:


\implies 2x=5

divide both sides by 2:


\implies x=\frac52
