Pratham enlarges an image of dimensions 37.5 cm × 25 cm on his computer in such a way that the dimensions of the enlarged image are in the same proportion as the original image. write the ratio of length to breadth in the lowest form (avoid decimals).

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 )

but which class are u may know that first
