Michelle is three times as old as Miguel. In seven years, Michelle will be twice as old as Miguel. How old are they now?

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 )

he answer is x=1x3 because x=1 to x=3

6 cars because if you have 8 and subtract 2 youll have 6 left over
