Question

3. Find
graphically
the coordinatep
of the vertice
triangle
whose sides have the equations:
2y-x=8,5y-x=14,y-2x=1​

Answer 1

Step-by-step explanation:

Algebraic solution:-

Let 2y-x=8 be equation 1

5y-x=14 be equation 2

2x-y=-1 be third

On solving 1 and 2,we get x=-4 and y=2

Coordinates of B = (-4,2)

On solving 2 and 3:

We obtain x=1 and y=3

Coordinates of C = (1,3)

On solving 1 and 3:

x=2 and y=5

Hence Coordinates of A=(2, 5)

Hope this helps

You can do the same by plotting these 3 equations on a graph paper with suitable scale and you will arrive at the triangle ABC.
