Isosceles trapezoid abcd has legs and and base if ab = 6y – 6, bc = 4y – 7, and cd = 7y – 12, find the value of y.

The description for an Isosceles trapezoid is that it has two opposites parallel, the two other opposites legs are equal and also the diagonals are equal.
side 1 = AB = 6y-6
side 2 = BC = 4y -7
side 3 = CD = 7y-12

When AB & CD are the two opposites and their measurement are equal. We will be we have:
AB=CD
6y-6 = 7y -12
Perform transposition method:
7y-6y=12-6
1y = 6
y=6

The answer for the "y" value is "6".

Ithink the answer is: it is likely.
