6.5
step-by-step explanation:
you said it was in the question
~courtney
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 )
d 600 because 15*10*2=300
300+300=600
