Intersection of line and plane!!!!!!!!!!!!!

Okay i to find the common points of line and plane

Question r=i+j+A(2k-j) and r . (i+j) = 4

2. Relevant equations

I heard that it is easier to use the vector equation in the form r . n = p

3. The attempt at a solution

So if i do that to above

You get

1 0 1

1 + A -1 . 1 =4

0 2 0

The above doesn't sound right i wont get an x, y, z value i defo need help on this or can anyone start my off

kind regards

And also how do you wrap the vectors in brackets on this forum lol
