To find the point of intersection...

sub y=6+x into the first equation

2(x+6)-3x=12.    then expand
2x+12-3x=12.     then simplify
-x=0.                   then multiply both sides by -1
x=0

Sub this x=0 into the second equation because its simpler

y=6+0

y=6

Answer (0,6) is the coordinate for the point of intersection (where the lines cross)

For these questions in GCSE if you can remember to Sub, Expand and Simplify, you will do great!
