3/2x-7=-11


We move all terms to the left:


3/2x-7-(-11)=0



Domain of the equation: 2x!=0


x!=0/2


x!=0


x∈R



We add all the numbers together, and all the variables


3/2x+4=0


We multiply all the terms by the denominator



4*2x+3=0


Wy multiply elements


8x+3=0


We move all terms containing x to the left, all other terms to the right


8x=-3


x=-3/8


x=-3/8

We have 2 congruent angles and 1 congruent side (AD = BC, given).

By ASA congruence, triangles AED and CEB are congruent.
