The sum of two numbers is 144 and the difference is 81. what ar the two numbers

yes yes yes yes yes yes yes yes yes

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

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 )
