Aroom is 15 feet long, 12 feet wide and 9 feet high. how much will it cost to remodel the room if carpeting costs $12 per square yard, a $22 can of blue wall paint covers 140 square feet and a $ 18 can of white ceiling paint covers 90 square feet ?

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 )
