#x = frac(1)(A) (2 d + e + y)#

We have: #A x - y = 2 d + e#

Let's add #y# to both sides of the equation:

#Rightarrow A x - y + y = 2 d + e + y#

#Rightarrow A x = 2 d + e + y#

Then, let's divide both sides by #A#:

#Rightarrow frac(A x)(A) = frac(1)(A) (2 d + e + y)#

#therefore x = frac(1)(A) (2 d + e + y)#
