A triangle is formed by the lines 2x –3y –6 = 0 ; 3x &ndas...
To find the coordinates of the vertices of the triangle, we need to find the points where the lines intersect.

First, let's find the intersection of the lines 2x + 3y = 6 and x - 2y = 4:

2x + 3y = 6
x - 2y = 4

Multiplying the second equation by 2, we get:

2x - 4y = 8

Adding this to the first equation, we eliminate x and get:

-y = 14

So, y = -14.

Substituting this back into the second equation, we get:

x - 2(-14) = 4

x + 28 = 4

x = -24

Therefore, the first vertex of the triangle is (-24, -14).

Next, let's find the intersection of the lines 2x + 3y = 6 and x + 4y = 8:

2x + 3y = 6
x + 4y = 8

Multiplying the first equation by 4 and subtracting the second equation, we get:

5y = -10

So, y = -2.

Substituting this back into the second equation, we get:

x + 4(-2) = 8

x = 16

Therefore, the second vertex of the triangle is (16, -2).

Finally, let's find the intersection of the lines x - 2y = 4 and x + 4y = 8:

x - 2y = 4
x + 4y = 8

Subtracting the first equation from the second, we get:

6y = 4

So, y = 2/3.

Substituting this back into the first equation, we get:

x - 2(2/3) = 4

x = 10/3

Therefore, the third vertex of the triangle is (10/3, 2/3).

To summarize, the vertices of the triangle are (-24, -14), (16, -2), and (10/3, 2/3).
