y=x+4
If you are tring to get "x" alone, you would do this:
y=x+4
-4 -4
--------
y-4=x
If you are trying to get "y" alone, then y=x+4 is your answer.
Y and X represent the 'Unknown Number'. For example, Y might mean the number 6 and X means the number 2, so then Y equals the same amount as X + 4 does which, in my example, is 6 but the numbers value to the letters (what the letter replacing the number is) changes from equasion to equasion. Generaly, somewhere written on the sheet it may say Y = 6 so then you would have to find out what X means, which in my example, is 2.

x=4 y=4
x = y = 0 ?
Symmetry, which states that if A = B then B = A Put A = 4 and B = x + y
x = 2y = 4

x=4 y=4
x = y = 0 ?
x = 0 and y = 4
y equals x plus 4 when y equals 0 then x equals 2i i is the square root of negative 1
symmetric property
Symmetry, which states that if A = B then B = A Put A = 4 and B = x + y
If X+Y=5;X=4, then x=4 and y=1
x=4 y=0

x=4 y=x+3 y=4+3 y=7
x = 2y = 4
