Astudent at university of maryland has 12 in her food plan account she bought a cheeseburger for 6.75 2 slices of cake for 1.25 each and a soda for 1.95 if she gets a side salad for 2.50 how much money is left in her account

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 )
