Four points A(6,3) , B(-3,5) , C(4,-2) , and D(x,3x) are given in such a way that

area of triangle DBC/area of triangle ABC =1/2. Find x

the given coordinates of the points are A(6,3) , B(-3,5) , C(4,-2) , and D(x,3x)

therefore the area of the triangle ABC is

since area of triangle DBC/area of triangle ABC=1/2
