x=1
explaination:
2x+3=5x
Subtract 5x from both sides.
2x+3−5x=0
Combine 2x and −5x to get −3x.
−3x+3=0
Subtract 3 from both sides. Anything subtracted from zero gives its negation.
−3x=−3
Divide both sides by −3.
x=
−3
−3
Divide −3 by −3 to get 1.

X=7. The two segments on the bottom as well as on the diagonal are the same length. This shows that the entire triangle and the inner triangle on the right are similar. So if we call the length of the bottom 2y, then 84/2y=6x/y. Solving this we get 84=12x, and so x=7
