2 y = x + 4
2 y = 14 s + 2
14 s + 2 = x + 4
14 s = x + 2
s = (1/14) (x + 2)

x=2y-4
=>x+4=2y
=>y=(x+4)/2
:.(y=7s+1)=((x+4))/2=7s+1)
=>x+4=14s+2
=>x+4-2=14s
=>s=x/14+1/7
This is 's' in terms of 'x'.

x+4=2y 7s+1=y
x+4=2y 14s+2=2y
then(transitive property)
x+4= 14s +2
x-14s= -2
x=14s-2

since y = 7s + 1, then substitute it in the x equation
x = 2(7s + 1) -4
x = 14s + 2 - 4
x = 14s -2 <=== answer

this is one of those "plug it in" problems
2(7s+1) - 4 = x
14s+2 - 4 = x
14s - 2 = x
not sure how much further u wanna go with that
