Let (2, y) divides line segment joining AB in m:n.

By space using space section space formula comma 2 equals fraction numerator 3 straight m minus 2 straight n over denominator straight m plus straight n end fraction space space space and space space space straight y equals fraction numerator 7 straight m plus 2 straight n over denominator straight m plus straight n end fraction 2 straight m plus 2 straight n equals 3 straight m minus 2 straight n space space space and space my plus ny space equals space 7 straight m plus 2 straight n straight m equals 4 straight n space space and space my plus ny space equals space 7 straight m plus 2 straight n  therefore open square brackets 4 straight n close square brackets straight y plus ny space equals space 7 open square brackets 4 straight n close square brackets plus 2 straight n 5 ny equals 30 straight n straight y equals 6
