u have
(x + 2)/2 - (y + 4)/3 = 4
now find a common denominator for the fractions, pick 6
then u get this
3 x - 6 - 2 y - 8 = 24 (1)
there is your first ecuation
now with

(x + y)/2 = 1/2 + (x - y/3)

pick 6 again
then we have
3 x + 3 y = 3 + 2 x - 2 y (2)

with (1) u get x = -5 y + 3
now use (2 ) with ur new x
then u have - 15 y + 9 - 2 y = 26
u got y = -1
now use y = -1 in (2)
u get x - 5 = 3
x is 8
