Please help! I'll mark Brainliest. I just need to know what G and F are! Or how to find them? I'm being timed!

G and F are the lines I guess? You have to use them to answer the rest of the questions.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

2+2 obliviously is 4.
