I am pretty sure this goes like this
Rearrange (i) so that x=4y+3-3y
Take (ii) and sub x
it will become 2(4y+3-3y)+4y= 18
Now use what you found for y in (iii) and sub in the (ii or i to get x)
lets take (i) 4y+3=3y+x
from (iii) 4(2)+3=3(2)+x
let me know if that's clear enough
Yes that is thank you so much (:
