To start with, we plug 55 in place of y in the equation:
55 = 5 + 2x.
Now we have to get x by itself. We start by examining the right-hand side. Remembering the order of operations (multiplication, then addition), the right-hand side can be interpreted as "two times x, plus 5."
We undo those operations in reverse order: we start by subtracting 5 from both sides.
55 - 5 = 5 + 2x - 5
This simplifies to 50 = 2x.
Now, we divide both sides by 2:
50 / 2 = 2x / 2
This simplifies to 25 = x, which is your answer. Hope that clears it up!

if y= 55
y= 5+2x
55=5+2x
collect the like term
55-5=2
50=2
divide both side by 2
25
therefore x =25.

Y=5+2X
SUBSTITUTING VALUE OF Y
55=5+2X
50=2X
X=25

Given:
Y = 5 + 2X .........................(1)
now placing the the value of y=55 that is given , in equation (1)
we have,
55 = 5 + 2X
55-5=2X
50=2X
50/2=X
25=X

Y = 5 + 2X
If Y = 55
55 = 5 + 2x
55-5 = 2x
50 = 2x
2x = 50
x = 50/2
x = 25
